Data Transfer to AWS from On-Premise Server

Part-1: Establishing an On-Premise Source Connection

On-Prem_cloud_integration_architecture
An illustration of the system which will be provisioned and configured.

Introduction

Migrating data from on-premise to the cloud can bring many benefits to an organization. It can reduce the cost of hardware and maintenance, improve scalability and availability, and enable access to advanced analytics and machine learning tools. Critical to this project is the creation of a source connection an the organisation's file server to a cloud-based object store via a file gateway.

The initial computing environment is set up by using the AWS CloudFormation service, along with the YAML version of its template language.

Step 1: Establishing Prerequisites

There are some prerequisite configuration processes that we'll need to follow in order to complete this project:

  1. Ensure you have access to an AWS account and IAM role with Admin privileges: We'll be required to configure a large number of resources and settings as part of creating the on-premise source connection. As such, having admin privileges associated with your IAM user is vital.

  2. Select the correct AWS region: All work to be completed within the eu-west-1 AWS region. Ensure that this region is used where applicable throughout the project.

  3. Conform to an appropriate naming convention: Wanting to monitor your work as you progress through this part of the challenge, use the following convention to name each service you configure: "DE{first 3 letters of your name capitalised}{first 3 letters of your surname capitalised}-{name of service}". For example, when configuring a VPC, and having the name "John Smith", the applied service name would be "DEJOHSMI-VPC".

  4. Generate a new key pair to access resources created within this part of the challenge: To securely log into the resources you create during the task (ensuring that no one tampers with our efforts), create a new key pair under the AWS EC2 service.

    • Set the name of key pair using the project naming convention, e.g. "DEJOHSMI-keypair".
    • Following this process should produced a .pem file for download. Store this file in a secure location for use later on in the project.

Step 2: Provisioning Infrastructure

With all the prerequisite setup actions completed, we are now ready to start building-out ourour environment. Instead of getting you to manually configuring the multiple resources required for this part of the project, we'll AWS CloudFormation - a service that allows us to manage infrastructure as code.

It is important to note that becoming familiar with CloudFormation will require an understanding of both the YAML language, as well as CloudFormation's template specific syntax.

2.1) Resource Links

So what is YAML and how can it be used alongside CloudFormation templates in order to generate infrastructure as code? To help us find answers to these questions, the following links will assist:

CloudFormation Templates

2.2) The On-Premise File Server

Resources Created

  • Linux Instance: A t2.micro EC2 instance, used to simulate the file server used within the on-premise source connection scenario.
  • IAM Role: An IAM role allowing an associated instance to access other AWS services.
  • S3 Access Policy: An IAM policy giving read-only access to any bucket within the S3 service.
  • Instance Profile: An IAM profile, connecting the instance and IAM role together.

Template Inputs

  • VPC: A VPC Id that defines which VPC the Linux instance will be deployed into.
  • Subnet: A Subnet Id defining which subnet to associate with the deployed Linux instance.
  • Security Group: A list of security group Id's which can be associated with the deployed instance.
  • KeyName: The name of a previously created AWS key pair which is associated with the Linux instance.
  • Linux AMI: The Amazon Machine Image (AMI) which is used to configure the EC2 instance. This input specifies the latest version of Amazon's Linux as the AMI to use.

2.3) Creating Additional Templates

First we need to generate a "VPC" base template which sets up the requisite network infrastructure into which the above resources can be deployed. We also need to write a second "Windows-instance" template which sets up the on-premise machine which can be used to access the file server declared in the above subsection.

Below a full list of the resources and inputs that need to be included in each of the respective templates:

VPC Template

  • Template Inputs: The following items represent fields which should be entered when spinning up the CloudFormation VPC template as a stack.

    • EnvironmentName: A string that will be prefixed onto each resource created in the template. This will be used to help identify the resources created during the project.
      • The default value for this input value should be DE-Extract.
    • VpcCIDR: The IPv4 address space, given in CIDR notation, for the VPC hosting the scenario challenge.
      • The default value for this input value should be 192.168.0.0/16
    • DataCenterPublicSubnetCIDR: The IPv4 address space, again given in CIDR notation, for the publicly accessible portion of the VPC.
      • The default value for this input value should be 192.168.10.0/24
  • Template Resources: The following items represent resources and their respective properties that should be configured and deployed within the VPC template.

    • VPC: An AWS virtual private cloud (VPC).
      • The VPC should inherit its CidrBlock address from the VpcCIDR template input.
      • The VPC should have both DNS support, and DNS host names enabled.
      • The VPC should be given a {key: value} tag of {"Name": EnvironmentName}, where EnvironmentName is part of the template input given above.
    • InternetGateway: An internet gateway, used to provide connectivity between the VPC and the internet.
      • The internet gateway should be given a {key: value} tag of {"Name": EnvironmentName}, where EnvironmentName is part of the template input given above.
    • InternetGatewayAttachment: An attachment that connects the above VPC and Internet Gateway.
      • The gateway attachment should reference both the InternetGateway and VPC above for its operation.
    • DataCenterPublicSubnet: Declares the public subnet of the VPC (portion of the VPC which can be accessed from the internet). This represents the portion of the data center network which we can log into as part of the project.
      • The subnet should inherit its VpcId from the VPC created above.
      • The first AvailabilityZone should be chosen for the subnet placement. Note: This assignment should be dynamic based upon which AWS region is chosen for the stack deployment.
      • The subnet's CidrBlock configuration should be inherited from the DataCenterPublicSubnetCIDR template input.
      • The subnet should automatically provide any new instances deployed within it a public IPv4 address.
      • The subnet should be given a {key: value} tag of {"Name": "DE-Extract Data Center Subnet"}.
    • PublicRouteTable: A route table for the configured VPC.
      • The route table should have its VpcId associated with the configured VPC above.
      • The route table should be given a {key: value} tag of {"Name": "DE-Extract Public Routes"}.
    • DefaultPublicRoute: Specifies a route in the above route table.
      • NB: This resource should only be created after the InternetGatewayAttachment above!
      • The route should inherit its RouteTableId from the above PublicRouteTable.
      • All destinations should be permitted as part of the route's DestinationCidrBlock.
      • It should inherit its GatewayId from the InternetGateway resource.
    • DataCenterPublicSubnetRouteTableAssociation: This resource associates the formed subnet with the route table configured above.
      • The route table association should be assigned the RouteTableId of the PublicRouteTable created in the script.
      • Its SubnetId should be that of the public subnet of the VPC (DataCenterPublicSubnet).
    • WindowsInstanceSG: The first of three security groups. This group permits RDP access to an instance deployed within the public subnet of the VPC.
      • The security group should have a VpcId associating it with the VPC created in this template.
      • It should be given a GroupName corresponding to DE-Extract-WindowsInstanceSG.
      • It should have an appropriately descriptive GroupDescription.
      • Regarding the group's SecurityGroupIngress, it should permit all tcp traffic to and from the default RDP port (3389), regardless of the source IPv4 address (corresponds to a CidrIp of 0.0.0.0/0).
      • The security group should be given a {key: value} tag of {"Name": "DE-Extract-WindowsInstanceSG"}.
    • FileServerSG: The second security group, which is responsible for permitting ssh access to the data center's file server from an internal source within the VPC.
      • Like the previous one, the file server security group should use its VpcId to associate with the VPC created in the template.
      • Its GroupName should be DE-Extract-FileServerSG.
      • As before, the security group should have an appropriately descriptive GroupDescription.
      • For this group's SecurityGroupIngress, it should permit all tcp traffic to and from the default ssh port (22). Unlike the previous security group, however, it should block any traffic from addresses outside of the public subnet of the VPC (corresponds to a CidrIp of 192.168.10.0/24).
      • The security group should be given a {key: value} tag of {"Name": "DE-Extract-FileServerSG"}.
    • FileGatewaySG: The last of the security groups, and the last resource of the template. This security group controls the access to the file gateway instance configured later on in this challenge.
      • As all the other security groups, the file gateway security group should use its VpcId to associate with the VPC created in the template.
      • It should have a GroupName of DE-Extract-FileGatewaySG.
      • It should also have an appropriately descriptive GroupDescription.
      • SecurityGroupIngress for the file gateway should permit tcp access to and from all ports on a given instance (ports 1 - 65534). However, only IPv4 addresses within the VPC should be able to communicate through the security group (corresponds to a CidrIp of 192.168.0.0/16)
      • Finally, the security group should be given a {key: value} tag of {"Name": "DE-Extract-FileGatewaySG"}

Windows-instance Template

  • Template Inputs: The following items represent fields which should be entered when spinning up the CloudFormation Windows instance template as a stack.

    • KeyName: A dropdown list enabling the selection of the key pair KeyName previously created in Step 1. This key pair is used to decrypt the Windows instance password generated on its instantiation.
    • VPC: A dropdown list enabling the selection of the Id for the VPC created in the previous template.
    • Subnet: A dropdown list enabling the selection of the Id for the public subnet created in the previous template.
    • SecurityGroupIds: A multi-selection list enabling the selection of one or more security groups created in the previous template.
    • LatestWindowsAmiId: A string-based resource path representing the latest Windows Amazon Machine Image (AMI) that should be used to create the remove instance.
      • NB: The Type of this input should be set to AWS::SSM::Parameter::Value<AWS::EC2::Image::Id>. This enables CloudFormation to select the latest version of the AMI specified within this input.
      • NB: The default value of this input should be set to /aws/service/ami-windows-latest/Windows_Server-2019-English-Full-Base. During the template's deployment, this value should be used and left unchanged.
  • Template Resources: The following items represent resources and their respective properties that should be configured and deployed within the Windows instance template.

    • WindowsInstanceRole: This is an IAM role that will be assigned to the Windows-based EC2 instance, allowing it to interact with other AWS services.
      • When the Windows instance stack is deleted, the role should be configured to automatically delete itself as well. (Hint: look into the DeletionPolicy attribute to define this behavior).
      • For the AssumeRolePolicyDocument trust policy, which defines the AWS entities that can assume the role, use the following configuration:
        • In the policy Statement, the Action should be sts:AssumeRole, and this should be allowed for the ec2.amazonaws.com service.
        • The version of the trust policy should be set to 2012-10-17
    • WindowsInstanceProfile: This is an IAM instance profile that allows our WindowsInstanceRole created above to be associated with an EC2 instance.
      • The Path of the instance profile should be set to /.
      • The profile Role should be associated with the WindowsInstanceRole.
    • WindowsInstanceRolePolicy: The IAM policy to be associated with the above-defined IAM role. This policy enables read-only access to all S3 buckets within your account.
      • When the Windows instance stack is deleted, the policy should be configured to automatically delete itself as well.
      • The PolicyName should be dynamically configured to be "Windows-client-{StackName}", where "{StackName}" should be substituted upon stack creation with the given name of the stack.
      • The policy should be associated with the WindowsInstanceRole declared above.
      • The PolicyDocument of the policy should allow the 's3:Get*' and 's3:List*' actions to be called on any resource. Its Version should be set to 2012-10-17
    • WindowsInstance: The Windows EC2 instance which represents an on-premise corporate machine which has network access to the private file server (Linux instance).
      • The ImageId of the instance should be the default value of the LatestWindowsAmiId template input.
      • The instance should be associated with the KeyName value specified within the template input.
      • The InstanceType should be set to t2.micro. Note: Using a different value will see additional costs being incurred for your AWS account!
      • The security groups to which the instance is assigned should be defined by the SecurityGroupIds template input.
      • The SubnetId to which the instance is associated should be given by the Subnet input of the template.
      • The IAM instance profile attached to the instance should be the WindowsInstanceProfile resource created above.
      • Finally, the instance should be given a {key: value} tag of {"Name": "DE-Extract-Windows-Instance"}

Name the completed VPC template file with the convention {firstname}-{surname}-VPC.yml, e.g. john-smith-VPC.yml. Follow the same convention for the Windows-instance template: {firstname}-{surname}-Windows-instance.yml. |

2.4) Launching Infrastructure via CloudFormation

After writing of your CloudFormation templates, its now time to see them come to life by launching them as stacks using the CloudFormation service.

We will launch the templates in the order given below. For each template, a handy list of values to specify for the input parameters during stack configuration, along with a representation of what the stack should look like is provided below when viewed through the Visual designer tool of CloudFormation:

1) VPC Stack Launch

Overview of CloudFormation dashboard
A visual representation of the deployed VPC infrastructure. The resulting visual produced within the Designer view should mirror this image.

  • Stack name: Use your challenge name designator as instructed in Step 1, action 3, e.g. JOHSMI-VPC.
  • EnvironmentName: Leave this as the default value of DE-Extract.
  • VpcCIDR: Leave this as the default value of 192.168.0.0/16.
  • DataCenterPublicSubnetCIDR: Leave this as the default value of 192.168.10.0/24.

No additional configurations are required for this VPC template.

2) Windows Instance Stack Launch

Windows EC2 CloudFormation Design View
A visual representation of the deployed Windows EC2 infrastructure. The resulting visual produced within the Designer view should mirror this image.

  • Stack name: Again, use your task name designator as instructed in Step 1, action 3, e.g. JOHSMI-Windows-Instance.
  • KeyName: Choose the name of the EC2 key pair created in Step 1, action 4, e.g. JOHSMI-keypair.
  • VPC: Choose the VPC configured in the previous template (should be tagged with 'DE-Extract' if launched correctly).
  • Subnet: Choose the subnet configured in the previous template (should be tagged with 'DE-Extract Data Center Subnet' if launched correctly).
  • SecurityGroupIds: Choose the security group tagged with 'DE-Extract-WindowsInstanceSG', as configured in the previous template.
  • LatestWindowsAmiid: Leave this as the default value of /aws/service/ami-windows-latest/Windows_Server-2019-English-Full-Base.

Note: This stack will ask for IAM role permission acknowledgement, but shouldn't require any additional configurations otherwise.

3) Linux Instance Stack Launch

Linux EC2 CloudFormation Design View
A visual representation of the deployed Linux EC2 infrastructure. The resulting visual produced within the Designer view should mirror this image.

  • Stack name: As done before, use your task name designator as instructed in Step 1, action 3, e.g. JOHSMI-Linux-Instance.
  • KeyName: Choose the name of the EC2 key pair created in Step 1, action 4, e.g. JOHSMI-keypair.
  • VPC: Choose the VPC configured in the initial template (should be tagged with 'DE-Extract' if launched correctly).
  • Subnet: Choose the subnet configured in the initial template (should be tagged with 'DE-Extract Data Center Subnet' if launched correctly).
  • SecurityGroupIds: Choose the security group tagged with 'DE-Extract-FileServerSG', as configured in the first template.
  • LatestLinuxAmiid: Leave this as the default value of /aws/service/ami-amazon-linux-latest/amzn2-ami-hvm-x86_64-gp2.

Again, this stack will ask for IAM role permission acknowledgement, but won't require any additional configurations.

Step 3: Setting Up a File Gateway

Having completed the setup of the scenario's infrastructure via CloudFormation, the next process in the task is the creation of a file gateway which will allow data to be seamlessly transferred into the cloud from the on-premise network (represented by the data center subnet of the VPC youwe've already configured).

In order to setup the file gateway appropriately, the following high-level actions should be followed:

3.1) Establish Connectivity with the On-Premise Windows Instance

The Windows EC2 instance we've configured is the only machine to which we should have public access (with the file server Linux instance being inaccessible via its assigned IPv4 address.) As such, many of the remaining configuration steps for the challenge should be completed while logged onto this Windows instance.

To connect to this instance, we need to make use of a Remote Desktop Protocol (RDP) client, along with the EC2 key pair configured in Step 1, action 4. Following this procedure should give us access to a live session on the Windows instance, wherein the desktop and Windows GUI can be seen.

3.2) Create an S3 File Gateway Resource Bucket

We now need to create an S3-backed file gateway for this challenge. This means that before we perform any more actions, we need to setup a new S3 bucket to act as a storage resource for the file gateway. Ensure that this bucket is not publicly accessible. The S3 service enforces all bucket names to be written in lower case, and to be globally unique. As such, extending the challenge naming convention, use 'de{full-first-name}{full-last-name}-source-file-gateway' as the unique name of your S3 bucket. For example, 'johnsmith-source-file-gateway'. Record this bucket name for later use.

3.3) Configure and Deploy an AWS File Gateway

We now need to create the File Gateway used in this scenario. This should be done by navigating to the AWS Storage Gateway creation page ("Services" > "Storage Gateway" > "Create gateway"), and complete the following attending steps for the Amazon S3 File Gateway setup.

  • Host Platform: When prompted to choose a host platform for the gateway, select the "Amazon EC2" option. This will lead you to configure a new EC2 instance as part of the setup process.
    • Ensure that the instance size is selected as c5.xlarge (smaller instances may lead to an unresponsive gateway).
    • Deploy the instance into the VPC and subnet configured within Step 2.
    • In order to provide cache storage for the gateway, add an additional 30 GiB EBS volume to the instance. This volume should be a general purpose SSD (gp2), and should terminate on deletion.
    • Give your instance and easily identifiable name tag using the challenge naming convention, e.g. "JOHNSMIT-filegateway".
    • When choosing the instance's security groups, select the existing "DE-Extract-FileGatewaySG" configured as part of the VPC stack in Step 2.
    • Once launched, record the private IPv4 address of the gateway host instance. This address will be used shortly to complete the setup of the file gateway.
  • File Gateway Activation: Note that once the host platform of the file gateway has been configured, the remaining steps of the file gateway setup must be completed from the Windows instance. Failing to do this will result in the activation of the gateway indefinitely timing out.
    • Ensure that the file gateway is configured with a "Public" service endpoint.
    • Follow the challenge naming convention to give the file gateway an appropriate name, e.g. "DEJOHSMI-filegateway".
    • After the gateway is activated, we need to configure its local disks and caching behavior. Here, when choosing a partition for cache, select the additional 30 GiB EBS volume created when configuring the gateway instance.
    • All other properties of the gateway should be left in their default state.
๐Ÿ’ธ Infrastructure Cost ๐Ÿ’ธ
While all services used up until this point have been within the free-tier of AWS, note that the creation of a c5.xlarge will incur a cost. As such, it is vital not to leave this instance running indefinitely, and that it is stopped it between working sessions on the project.

Step 4: Configuring and Mounting the NFS File Share

Having provisioned a file gateway, the next logical step is to set up a corresponding file share that will be responsible for receiving data during the on-premise to cloud migration. Here we provision an NFS-based file share in this regard, and that it should be mounted to the on-premise's file server (Linux instance) in order to facilitate seamless data transfer to the cloud.

4.1) NFS Creation

The following high level guidance is given to help accomplish the creation of the NFS-based file share:

  • Create the file share via the AWS Storage Gateway File shares dashboard ("Services" > "Storage Gateway" > "File shares".)
  • When prompted to provide the file gateway to associate the share with, select the option corresponding to the gateway instance set up above.
  • Use the S3 bucket configured in Step 3.2 as the storage resource for the file share. Do not specify an additional prefix name for the bucket.
  • Limit access to the file share by specifying a CIDR block address of 192.168.0.0/16 for allowed hosts.
  • Configure the "Squash level" of the file share to be "No root squash". In essence using this option allows a root user on a remote node to access EVERYTHING on the NFS server that is available.
  • Once successfully created, retrieve the Linux-based connection command for the file share. This can be found by navigating to the "Example Commands" section under the created file share's AWS management console dashboard entry.

4.2) File Server Connection and NFS Mounting

We now need to connect to the remote file server of the organisation (Linux instance) via ssh in order to mount the newly created NFS file share onto it.

  • WE can only connect to the file server via the Windows instance. As such, we need to use the ssh command from this machine to perform the mount operation.

    • We need to copy the EC2 key pair .pem file (configured in Step 1, action 4) onto the Windows instance in a known location to use the ssh command successfully.
    • The following generic command can be used to perform the ssh connection. Take care to replace the {curly brace} values with your own details, and to issue this command from the same folder that the .pem key pair file is stored in:
    ssh -i {your-key-file-name}.pem ec2-user@{Linux-Instance-Private-IP}
  • Once successfully logged onto the Linux instance, modify the Linux-based connection command obtained in Step 4.1 above in order to mount the NFS file share.

    • Ensure that all commands are performed as the root user sudo on the Linux instance.
    • The mount target for the file share should be the /nfs_source folder that already exists on the Linux instance.
    • Once the mount command has been run, we can validate its success by running df -h as a command within the terminal. If successful, we should see an additional volume added to our instance's storage devices with the same name as the file share configured previously.

Step 5: Configuring Alarm Triggers

Having mounted the NFS file share onto the Linux instance file server, we do like to be alerted every time data is transferred from the instance through the file share. To do this, she advises you to configure a metric-based CloudWatch alarm which will trigger when a data transfer over a specified threshold is exceeded.

Some implementation details here include:

  • Configure the alarm using the AWS Cloudwatch alarm creation page ("Cloudwatch" > "Alarms" > "Create alarm").
  • When prompted to choose an appropriate metric for the alarm, search for and select the 'Storage Gateway > File Share Metrics' grouping.
  • Select the 'CloudBytesUploaded' metric corresponding with your configured file gateway.
    • For this selected metric, set its 'Statistic' to be calculated as a 'Sum' over a 1 minute period.
    • Set a value of 50'000 (50 KB) to be the threshold value for the metric.
  • As a form of notification whenever the alarm is raised, choose to send a message via a newly created SNS topic.
    • For the topic name, use the challenge naming convention followed by '-Fileshare-alert'. For example: 'DEJOHSMI-Fileshare-alert'.
    • Use the following addresses when designating email endpoints to to receive the alert notification:
      • Your own personal email account. This will allow you to troubleshoot the alarm's operation during development.
      • Note that you'll need to confirm your email address before you are able to receive notifications from the SNS service.
    • When prompted to add a name and description to your notification, configure your "Alarm name" using the format "{Name-Surname_File-transfer-success}". For example, with the given name "John Smith", the alarm name would be "John-Smith_File-transfer-success". Leave the 'Alarm description' field blank.

Step 6: Testing Your System

With CloudWatch alarm configured and the file share mounted, we now need to transfer data to the mounted NFS file share in order to assert its correct operation, and thereby trigger the CloudWatch alarm as well. To do this, log onto the file server via the Windows instance and navigate to the file server's data repository by entering the following command:

cd /predict_data/Individual_Stocks/

Review the contents of the folder by using the ls command. This should display a large list of .csv files.

Now copy these files to the file share previously mounted. This action represents the secure transfer of files from the local, on-premise, file server, to your remote S3 bucket, acting as storage within the Cloud. To perform this action, run the following command:

sudo cp -a /predict_data/Individual_Stocks /nfs_source/

If this command returns no output, then it should have executed successfully. You can validate this success by navigating to the NFS mount and inspecting the files contained within:

ls /nfs_source/Individual_Stocks/

CSV files transferred onto the NFS-based file share.
CSV files transferred onto the NFS-based file share.

If the output of this command is a long list of various .csv files, then the transfer has indeed been SUCCESSIFUL.

๐Ÿšฉ Tear Down ๐Ÿšฉ

Here is a checklist of services which will need to be terminated as part of the clean-up process:

CloudFormation: The stacks created in Step 2 can be deleted navigating to the Stack dashboard ('CloudFormation' > 'Stacks'), selecting your stack, and clicking on 'Delete'. This action will delete all the associated infrastructure setup in the stack deployment. Stacks to delete:

  • VPC stack
  • Windows remote instance stack
  • Linux remote instance stack

S3: The storage resource bucket associated with the file share can be deleted by navigating to the S3 dashboard, selecting the file share bucket, and clicking on 'Delete'. Note that you will need to empty the bucket before this operation is successful.

File Gateway: Several components would have made up the configured file gateway. Each of these should be terminated individually to ensure no additional billing occurs:

  • Storage gateway instance, as configured in Step 3.
  • NFS-based file gateway, as configured in Step 4. To do this, navigate to the 'File shares' dashboard, select the file share, and under 'Actions' select 'Delete file share'.
  • Storage gateway service. Even with the underlying EC2 instance removed, you'll still need to manually terminate the storage gateway itself. Here, navigate to the 'Gateway' dashboard, select the storage gateway, and under 'Actions' select 'Delete gateway'.

CloudWatch Alarm: To remove the automated notification alarm, simply navigate to the CloudWatch 'Alarms' dashboard, select your configured alarm, and under 'Actions' select 'Delete'.

๐Ÿ’ธ Infrastructure Cost ๐Ÿ’ธ
Even though the majority of resources set up for this project are in the AWS free tier, it's vital that you shut them down carefully. Missing this step can mean that long-running resources exceed their free-tier quota, and result in unforeseen account charges being incurred!
