Cloud computing is proliferating each passing year, meaning that there are plenty of opportunities. Creating a cloud solution calls for a strong architecture. If the foundation is not solid then the solution faces issues of integrity and system workload. AWS's five pillars help cloud architects to create a secure, high-performing, resilient and efficient infrastructure.
In this post, we'll take a look at the five pillars of AWS well-architected framework.
This pillar is a combination of processes, continuous improvement, and monitoring system that delivers business value and continuously improve supporting processes and procedures.
- Perform operations as code: Define the same engineering discipline that will be used for application code for the entire workload infrastructure.
- Annotate documentation: Automate documentation on every build which can be used by systems and humans.
- Make frequent, small, reversible changes: Design infrastructure components to apply changes in small size increments on a regular interval.
- Refine operations procedures often: As operations procedures are designed, we should keep checking and evaluating the process for the latest updates.
- Anticipate failure: Perform tests with pre-defined failure scenarios to understand its impact. Execute such tests on regular interval to check the infrastructure with simulated events.
- Learn from all operational failures: Keep track of all failures and events.
Security pillar centers on protecting information, systems, and assets along with delivering business needs.
Implement a strong identity foundation
Implement the least privilege and enforce authorized access to AWS resources. Design central privilege management and reduce the risk of long-term credentials.
Enable Traceability and Security Events
Monitor, alert, and audit incident response of actions and changes in environment real-time. Run incident response simulations and use automation tools upsurge speed for detection, investigation, and recovery.
Apply Security at All Layers
Apply security to all layers, like the network, database, OS, EC2, and applications. Prevent application and infrastructure by human and machine attacks.
Automate Security Best Practices
Create secure architectures, including implementation of controls that are defined, software-based security mechanisms and managed as code in version-controlled templates.
Safeguard Data in Transit and At Rest
Categorize data into sensitivity levels and mechanisms, such as encryption, tokenization, and access control.
Keep People Away from Data
Create mechanisms and tools to reduce or eliminate the need to direct access or manual processing of data to reduce the risk of loss due to human error.
The Reliability pillar ensures that a given system is architected to meet operational thresholds, during a specific period of time, meets increased workload demands, and recovers from failures with minimal or no disruption.
Test Recovery Process
Use automation to simulate different failures or to recreate scenarios that led to failures. This reduces the risk of components that are not been tested before failing.
Automatic Recovery from Failure
Enable the system monitoring by KPIs, triggering automation when a threshold is reached. Enable automatic notification and tracking for failures, and automated recovery processes that repair the failure.
Scale Horizontally to Increase Aggregate System Availability
Replace one large resource with multiple small resources to reduce the impact of a single failure on the overall system.
Stop Guessing Capacity
Monitor demand and system utilization and automate the addition or removal of resources to maintain the optimal level.
Manage Change in Automation
Changes to infrastructure should be done via automation.
Performance Efficiency focuses on ensuring a system/workload delivers maximum performance for a set of AWS resources utilized (instances, storage, database, and locality)
Democratize Advanced Technologies
Use managed services (like SQL/NoSQL databases, media transcoding, storage, and machine learning) that can save time and monitoring hassle and the team can focus on development, resource provisioning, and management.
Go Global in Minutes
Deploy the system in multiple AWS regions around the world to achieve lower latency and a better experience for customers at a minimal cost.
Use Serverless Architectures
Reduce overhead of running and maintaining servers and use the available AWS option to host and monitor infrastructure.
Experiment more often
With a virtual and automated system and deployment, it is very easy to test system and infrastructure with different types of instances, storage, or configurations.
Cost optimization focuses on achieving the lowest price for a system/workload. Optimize the cost while considering the account needs without ignoring factors like security, reliability, and performance.
Adopt a Consumption Model
Pay only for the computing resources you consume and increase or decrease usage depending on business requirements are not with elaborate forecasting.
Measure Overall Efficiency
Measure the business output of the system and workload, and understand achieved gains from increasing output and reducing cost.
Adopt Managed Services and Stop Spending Money on Data Center Operations
Managed services remove the operational burden of maintaining servers for tasks like sending email or managing databases, so the team can focus on your customers and business projects rather than on IT infrastructure
Analyze and Attribute Expenditure
Identify the usage and cost of systems, which allows transparent attribution of IT costs to revenue streams and individual business owners.
Using the AWS Well-Architected Framework and following above discussed practices, one can design stable, reliable, and efficient cloud solutions fulfilling business needs and value.
