Thinking of getting started with AWS cloud computing or migrating your existing workloads to AWS? Here is a quick guide on how the 5 pillars of AWS’s well-architected framework will help you build a secure, high-performing, resilient and efficient cloud infrastructure for your workloads.
So basically, the AWS well-architected framework describes the main design principles, concepts, and the best architectural practices to run your workloads in the AWS cloud.
The 5 pillars of AWS's well-architected framework are:
Let’s take a closer look at each of these pillars.
The Operational excellence pillar outlines how DevOps /cloud teams should run and monitor systems to deliver business value and to continually improve supporting processes and procedures in order to deliver business value.
To achieve these objectives, the operational excellence pillar utilizes the following principles:
The entire cloud environment can be defined as code. Operations procedures can also be defined as code and updated as code. This helps in limiting human error and enabling consistency in event response.
This makes it easy to determine the cause of a problem if it occurs as compared to making large changes all at once. The reverse changes made should not affect customers — if possible.
Frequently reviewing operations procedures helps the entire team to be familiar with them and participate in areas that can be updated.
In order to ensure future failures are curbed, the team should carry out a pre-mortem exercise to assess where failure could occur.
Sharing with the team past failures helps to derive key lessons to be learnt.
The security pillar focuses on setting mechanisms that protect data, systems and assets.
There are 7 key design principles that help in enhancing security in the AWS cloud. These are:
Here the principle of least privilege is implemented and separation of duties enforced.
Metrics collection and log integration help in investigation and remediation in the event a problem occurs.
Ensure security is applied in all aspects of cloud infrastructure; compute, storage, networks etc
Automation helps to scale easily, quickly and in a secure way in the cloud.
Data should always be protected whether in transit or at rest using the appropriate controls. These controls include tokenization, encryption and access control.
This involves eliminating the need to access data directly or process data manually. Ultimately the risk of mishandling data, modification or human error is eliminated.
In case of a security event, ensure there is speedy detection, investigation and recovery through the use of automation and response simulations.
A well-architected framework outlines mechanisms for any application or system to provide services to users or customers when expected to.
To achieve this the reliability pillar has 5 design principles:
Based on the needs of a business, there may be requirements in place to have recovery control in place and the time taken to recover to be very minimal.
A successful backup can only be termed as so when restoration can be done successfully.
In order for change to occur, there should be a proper plan, documentation, testing, approval and a backup plan in case the changes made break the environment.
Use only the capacity needed for production and avoid saturation or over-provisioning.
This simply eliminates a single point of failure.
AWS defines availability as a percentage uptime such as 99.9% over a period of time mainly a month or year.
The performance efficiency pillar guides the effective use of computing resources to meet system and business requirements.
The performance efficiency pillar revolves around five design principles:
You may want to consider consuming some of the advanced technologies as a service. This helps you to focus on developing the product rather than provisioning resources and managing them.
By leveraging AWS’s global footprint, deploy your applications to multiple regions to reduce latency and for a better customer experience.
Serverless architecture helps you to run code directly without running and maintaining the servers used.
Doing experiments more often helps to discover which configuration works best for the business.
Use an approach that aligns best with your goals from a data-centric perspective.
The cost optimization pillar aims at providing optimum and resilient business solutions at the lowest possible cost to the user. When using cloud services, money is spent on services used.
There are 5 principles that guide users in cost optimization:
This helps to pay only for services used and to scale upwards or downwards based on demand.
Use tracking metrics to assess the business output of the workloads you are running. This will increase efficiency and overall performance.
Let AWS do all the heavy lifting of data centre operations such as racking and powering servers. Your main focus should be on customer and business logic.
For accurate return on investment calculations, AWS cloud makes it easy to identify the cost and usage of workloads attributed to specific departments.
Cloud financial management should be set as one of your company’s financial goals. This will accelerate business value and help achieve financial success.
