In 2019, cloud computing is predicted to zoom like a rocket. Consequently, the cloud market is set to evolve, primarily due to the high demand and rising adoption. In a high-level business environment, the primary challenge is to test the scale. When you go into production, you may face a whole new class of issues.
It usually happens when architectural experimentation is done manually at the start of a project. Monolithic architectures are difficult to manage, and it becomes hard to even think about making a change. This means, you cannot make informed decisions.
In AWS these constraints have been removed. It promises complete scalability, agility, and freedom with smart design principles for your systems. Let’s explore in detail how the five fundamental pillars of the AWS Well-Architected Framework can lead to significant benefits.
1. Operational Excellence
You can gauge the operational excellence of a workload by its reliability, agility, and performance. It includes the ability to run systems and gain insights into their operations. The best way forward is to manage and automate changes, respond to events, and run sustained operations.
Six design principles to help drive operational excellence:
- Perform operations as code: In AWS you can apply the same engineering designs that you use for application coding. You can define your entire workload as code, script operations and automate their execution by triggering them in response to events. By performing operations as code, you eliminate human errors and enable consistent responses to events.
- Annotate documentation: In an on-premise environment, documentation is usually created manually, and it’s hard to keep up with the pace of change. In AWS you can automate the creation of annotated documentation after every build.
- Refine operations procedures frequently and make small, reversible changes: You can make changes in small increments that can be reversed if they fail to aid the identification and resolution of issues introduced in your environment. This increases the flow of beneficial changes to your workload.
- Anticipate failure: Find out potential sources of failure, so that they can be removed or mitigated. Test for responses to unexpected events to understand the impact. Set up regular game days to test your workloads and team responses to simulated events.
- Learn from all operational events and failures which will help you keep operations procedures current.
Security is a critical aspect of your cloud infrastructure. The key topics include confidentiality, the integrity of data, identification and managing privilege management, protecting systems and establishing control of the data security events.
To protect your system from critical threats, AWS suggests the following design principles:
- Implementation of a strong identity foundation: Implement the principle of least privilege for separation of duties with the appropriate authorization for each interaction with AWS resources. With centralized privilege management, you can reduce or even eliminate the lines on long term credentials.
- Enable traceability: Monitor, alert, and audit access and changes to your environment in real time. Integrate loads and metrics with systems to automatically respond and take actions.
- Apply security to all layers: Rather than focusing on the protection of a single layer, you apply defence and depth approach with other security controls and use it at all levels.
- Automate security best practices: Automated security mechanisms improve your ability to scale cost-effectively. You can create secure architectures including the implementation of controls that are well defined and managed.
- Always protect data: Use encryption, tokenization, and access control where appropriate. Create fundamental mechanisms and tools to reduce the need for manual processing of data. This reduces the risk of loss and human error while handling sensitive data.
- Prepare for security events: Establish an effective incident management program that aligns with your organizational requirements. Run incident response simulations and use tools with automation to increase your detection speed, investigation, and recovery.
It focuses on the system to recover from infrastructure or service disruptions, acquire computing resources, and mitigate disruptions. Key topics include foundational elements around set up, cross-project requirements, recovery planning and change handling.
Below are five design principles for reliability:
- Test recovery procedures: You can test how your systems fail and leverage automation to simulate different failures or re-create scenarios that led to failures previously.
- Automatically recover from failure: By monitoring systems for KPIs, you can trigger automation when the threshold is breached.
- Scale horizontally to increase aggregate system availability: You can replace one large resource with numerous small resources to minimize the impact of a single failure.
- Stop guessing capacity: You can monitor demand and system utilization and automate the addition or removal of resources to maintain the optimal level to satisfy demand.
- Manage change in automation
4. Performance efficiency
It focuses on using computing resources to meet requirements and maintain efficiency as demand changes and technologies evolve. The key topics include selecting resource types and sizes based on workload requirements, monitoring performance, and making informed decisions to maintain efficiency as business needs change.
AWS recommends these design principles for performance efficiency:
- Democratize advanced technologies: Technologies which are challenging to implement can be easier to consume by pushing analogy complexity into the cloud. Rather than having your IT team host new technologies, they can simply consume it as a service. In AWS these technologies become services for your team to consume. This eliminates resource provisioning and management.
- Go global in minutes: You can quickly deploy your systems across multiple AWS regions around the world with just a few clicks. It will lower latency and provide a better experience for your customers at minimal costs.
- Use serverless architectures: In AWS you don’t need to maintain servers that carry out traditional computing activities. It also lowers transactional costs when managed services are operated at cloud scale.
- Try out comparative testing as well as various configurations to explore what performs better.
5. Cost Optimization
The focus is more on eliminating unused or sub-optimal resources. You should consider matching supply with demand while using cost-effective resources and being aware of the expenditure.
It can be achieved by the following design principles:
- Adopt a consumption model: You pay only for your computing resources and can increase or decrease your usage depending on your business requirements.
- Measure overall efficiency: You measure the business output of systems and cost associated in delivering it.
- Eliminate data center operations costs: AWS does all the heavy lifting so that you can focus on business projects and your customers.
- Analyze and attribute expenses: The cloud helps in identifying the usage in costs and systems accurately. It allows for transparent attributions for IT costs to individual business owners. This helps measure ROI and enable system owners to optimize their resources and reduce costs.
- Use managed services to reduce the cost of ownership: Managed services in the cloud remove the operational burden of maintaining servers for tasks like sending an email, managing databases. Since managed services operate at cloud scale, they can offer lower costs for transactions and servers.
As organizations look to leverage the full potential of AWS cloud, it is essential to align with architecture best practices and ensure compliance with design principles of the five fundamental pillars.
