Managing Change With AWS

The AWS (Amazon Web Services) Well-Architected Framework encompasses the five pillars, Operational Excellence, Reliability, Performance Efficiency, Cost Optimization, and Security. By following each pillar’s best practices, you can implement designs that will scale with your business.

The AWS Well-Architected Framework helps you mitigate risks, build and deploy architectures faster, and make informed decisions.

AWS Framework and Reliability

The second pillar within the AWS Well-Architected Framework is reliability, which refers to a workload’s ability to perform consistently and correctly. Within the reliability pillar, these are the design principles to keep in mind for best practices:

Automatic failure recovery
Monitoring KPIs (key performance indicators) allows you to be notified immediately if a threshold is crossed or significant change occurs.

Procedures for test recovery
Testing how your workload might fail in the cloud allows you to see your recovery procedures’ effectiveness.

Scale horizontally
Distribute the workload across more small resources to decrease the impact of a single point of failure.

Stop guessing capacity
Accurately monitor demand to avoid over-saturating the workload.

Manage change in automation
Change infrastructure using automation.

Change Management
Change management is a critical aspect of maintaining reliability with AWS. Effectively managing change comes down to monitoring, preparing to adapt and implement the changes.

Monitoring Workload Resources
It’s possible to configure your workload to monitor performance metrics and provide updates if a major event or change occurs. The benefit of accurate performance monitoring is that you can respond quickly when negative changes occur, such as a low-threshold crossing or a system failure.

Monitoring comprises four phases which are generation, aggregation, real-time notification, and storage. In the generation phase, monitoring occurs for all parts of the workload, while aggregation refers to interpreting this data. Real-time processing allows you to have a timely response to changes in data.

The storage phase provides access to past logs for analysis of data on a larger scale. Effective monitoring means you can adapt to changes quickly.

Designing Your Workload to Adapt
You can use AWS services to automate scaling of your workload. A workload must be scalable because this provides flexibility to adapt to changes in function or performance by adding or removing resources.

Implementing Change
Changes that occur in the workload must be intentional. Run tests to ensure you can roll back a deployment at any time without disrupting service to your customers. This includes functional and resiliency testing performed in the pre-production pipeline to determine how changes you implement will impact the system.

How AWS Helps with Designing Operational Excellence

The AWS Well-Architected Framework is a system that helps build secure and efficient infrastructure in your company’s applications and workloads. It uses five pillars, operational excellence, security, reliability, performance efficiency, and cost optimisation, to streamline your workloads in the cloud.

By completing an AWS Well-Architected Review using WOLK, a Well-Architected Partner, you can ensure your application and workloads are working at their highest potential.

Operational Excellence: The First Pillar

Operational excellence is the first of five pillars in the AWS Well-Architected Framework. In this pillar, the Framework focuses on supporting business objectives, effectively running workloads, learning more about specific operations, and the ability to continue to improve procedures.

Within the pillar are five design principles: Perform operations as code, make frequent, small, reversible changes, refine operations procedures frequently, anticipate failure, and learn from all operational errors. With the AWS Well-Architected Tool, you can discover which of these principles need to be improved.

1. Perform Operations as Code

Performing all operations as code lowers the likelihood of human error from the entire workload. It creates a more streamlined system that can be easily updated and allows a faster response time.

2. Make Frequent, Small, Reversible Changes

Instead of making sweeping changes to fix a problem, the AWS Well-Architected Framework suggests beginning with small, reversible changes. If there is a problem, a small change is easily correctable and costs less time and money to address.

3. Refine Operations Procedures Frequently

Every time your business evolves, so should your operations procedures. Schedule regular meetings to ensure your workload is operating as efficiently as possible.

4. Anticipate Failure

Before starting, plan alternative options. Even after a system is in place, it can fail for many reasons. If your business has backup plans and a response plan in place, you can minimise any negative effects of a failure.

5. Learn from all Operational Failures

Just like a company should anticipate failure, a company should learn from it. Analyse the failure, and create new procedures to protect against it in the future.

Working with a Well-Architected Partner

WOLK is a leading partner of the AWS Well-Architected Program and is fully certified to provide AWS Well-Architected Reviews. After the review, which will highlight high-risk items, WOLK will begin the remediation stage.

The Best 6 Ways to Secure Your Business Information

AWS’s Well-Architected Framework offers comprehensive cloud computing services to businesses through its five pillars.

The second pillar, Security, contains methods for protecting company data, operational systems, and assets through cloud technologies. By utilising the Security pillar’s design principles and best practices, businesses can effectively secure their information with minimal risk.

Security Pillar Design Principles

AWS developed seven design principles to help shape the framework:

1. Create a clear identity foundation
2. Enable traceability across all systems
3. Apply security measures at all system layers (e.g. on all systems, applications, codes etc.)
4. Automate security where possible
5. Protect data in storage and during transfers
6. Eliminate the human role in processing data where possible
7. Prepare for security incidents

Ways to Secure Business Information Through AWS

1. Employ the Best in Practice Security Services

Use AWS services to ensure all aspects of your business information is protected as much as possible. Staying up to date with the latest technologies and recommendations helps keep your intelligence threat level low. Automation, testing, and evaluation provide opportunities to scale.

2. Identity and Access Management

Identity and access management are critical in securing important business information. It makes sure that only authenticated employees can gain access to certain data. This can be managed through an AWS Identity and Access Management (IAM) service.

3. Detection Technology

AWS detection technology, such as CloudTrail logs, allows for processing and auditing various systems, meaning you can detect security breaches or information security threats early.

Log management is key in maintaining a Well-Architected workload, particularly if a security incident occurs. Logs can be analysed and acted on in such scenarios.

4. Infrastructure Protection

Infrastructure protection refers to information security on the cloud and on-premises. It involves AWS native or AWS integrated services that protect, monitor, and log information from points of ingress and egress linked to sensitive business information.

5. Data Protection

Before you can develop any architectural system, fundamental data protection measures should be in place. AWS services can then be used to make data encryption easier, adding further protection.

6. Incident Response

No matter how comprehensive your security systems may be, you should always have an incident response plan in place in case of a security issue. Your company can implement AWS systems to create a fast and effective incident response function.

Tools such as AWS CloudFormation allow you to write or change AWS resources in a safe environment, keeping your information safe.

The Top 4 Ways to Use AWS to Improve Performance Efficiency

Amazon Web Services (AWS) employs a five pillar framework to guide and assist businesses in adopting continuous best practices through cloud services. You can use these conceptual pillars to improve the performance efficiency of a business.

The Performance Efficiency pillar is most crucial in developing performance. It involves using computing resources to improve the efficiency of a business’ systems and subsequently to sustain efficiency as the market changes and technologies advance.

At WOLK, we are AWS experts. With many years of experience designing complex network architecture, our team can help you leverage AWS to improve the performance efficiency of your business.

1. Allows Your Team to Focus on Core Competencies

Through the design principles of Performance Efficiency, businesses can use technology as a service rather than assigning members of their IT team to the task of learning, hosting, and running new technological services. Technologies such as NoSQL, a database that stores and retrieves data, can fulfil complex tasks quickly and efficiently, allowing members of your team to focus on the core competencies of your business. NoSQLs are used more in big data and real-time applications as they are faster and more flexible than other types of databases.

2. Lower Costs Through Serverless Architectures

Another product of the design principles of Performance Efficiency is the use of serverless architecture. This eliminates the need to operate using physical servers, which can be a tedious and costly operation. By managing services via the cloud, businesses can lower their costs, improving performance efficiency.

3. Optimise Architecture Through Service Selection

There are many types of AWS resources, from standard databases to artificial intelligence (AI) and data lakes. Through these systems, you can create and optimise an architecture to best suit your workload. Organisations can use data analysis software to find the most useful programs for their specific business or industry. AWS Partner Network (APN) suggests architecture selections based on industry knowledge. For example, it may recommend that you use Amazon Elastic Block Store for low-latency block cloud storage.

4. Improve Efficiency Through Innovation

Reviewing and monitoring are two of the best practices of Performance Efficiency. AWS is constantly innovating to meet customer demands. Through new innovative AWS services, regions, edge locations and other features, you can improve performance efficiency. Once you have implemented a new workload, you must monitor it and analyse its performance. AWS services like Amazon CloudWatch can monitor a workload and provide you with information and actionable insights, helping you determine opportunities to improve efficiency.

How moving to AWS improves security for your entire organisation.

There are many good reasons why so many large organisations have moved their operations to the Amazon Web Service (AWS) cloud platform. We touched on a few of them in a previous blog. But possibly the most important benefit AWS offers organisations is a first-rate security framework, security being one of the 5 pillars we’ve touched on before.

The security pillar of AWS is designed to “protect information, systems, and assets while delivering business value through risk assessments and mitigation strategies”.


The security pillar is based on the following seven design principles:

1) Implement a strong identity foundation: Implement the principle of least privilege and enforce separation of duties with appropriate authorization for each interaction with your AWS resources. Centralize identity management, and aim to eliminate reliance on long-term static credentials.

2) Enable traceability: Monitor, alert, and audit actions and changes to your environment in real time. Integrate log and metric collection with systems to automatically investigate and take action.

3) Apply security at all layers: Apply a defense in depth approach with multiple security controls. Apply to all layers (for example, edge of network, VPC, load balancing, every instance and compute service, operating system, application, and code).

4) Automate security best practices: Automated software-based security mechanisms improve your ability to securely scale more rapidly and cost-effectively. Create secure architectures, including the implementation of controls that are defined and managed as code in version-controlled templates.

5) Protect data in transit and at rest: Classify your data into sensitivity levels and use mechanisms, such as encryption, tokenization, and access control where appropriate.

6) Keep people away from data: Use mechanisms and tools to reduce or eliminate the need for direct access or manual processing of data. This reduces the risk of mishandling or modification and human error when handling sensitive data.

7) Prepare for security events: Prepare for an incident by having incident management and investigation policy and processes that align to your organizational requirements. Run incident response simulations and use tools with automation to increase your speed for detection, investigation, and recovery.


The design principles lay the foundation for the five focus areas of the security pillar:

1) Identity and access management
2) Detective controls
3) Infrastructure protection
4) Data protection
5) Incident response

There is plenty of overlap through these focus areas so it is important to consider how each area can build on or influence others. They should be viewed together as integrated components of your security program rather than individual siloed processes.

Why should all this matter to your organisation?

AWS offers a level of investment and expertise in cloud security that most organisations could not hope to achieve on their own. A few benefits include:

1) The most advanced digital security available.

2) AWS is scalable in every respect, so if there’s a change to your security needs, you can be sure you won’t “outgrow” AWS and need to look for another provider.

3) AWS customers number the tens of thousands, including leading financial organisations and government agencies, so you can be sure that your data is the safest it can be.

Cloud security is top-of-mind for organisations moving their workloads to the cloud or managing an existing application in the cloud. Reviewing an existing or planned application against the principles of the Security Pillar can help you determine what action your organisation needs to take to improve deficiencies and be as secure as possible.

The Ultimate Guide to Enhancing Performance Efficiency

The AWS Well-Architected Framework uses the premise of five operational pillars, Operational Excellence, Security, Reliability, Performance Efficiency, and Cost Optimisation. The AWS secure cloud services platform provides data storage, content delivery and compute power, among other services that benefit workloads. Using AWS, you can host applications in the cloud and deliver efficient, exciting websites to clients.

The Fourth Pillar
The Performance Efficiency pillar is the fourth pillar of the Well-Architected Framework, and it focuses on the proper allocation of resources to meet system requirements as changes occur.

To understand how to distribute resources for the optimal system response, it’s necessary to understand how the AWS Well-Architected framework functions. Knowledge of the other pillars, particularly Reliability and Cost Optimisation, will be exceptionally helpful in determining how you can use your resources most efficiently.

Improving Performance Efficiency With AWS
To maximise your workload’s performance efficiency using AWS, you must constantly review your selections because of the ever-changing nature of the cloud and newly available features.

To enhance efficiency in the cloud, there are five design principles you can follow:

● Global Deployment
When you deploy your workload to various AWS regions across the globe, you can decrease latency levels and minimise costs for maximum efficiency.

● Make it Accessible
You can make life easier for your team by assigning complex tasks to the cloud vendor instead. The technologies in the cloud become services for your team so they can direct their efforts to developing products.

● Make Use of Serverless Architectures
Going virtual means you no longer have to run and maintain a physical server in one location. Static websites and event services can host your system code, reducing the human power required for the system and minimising expenses.

● Experiment Frequently
Using various types of storage, configurations, and instances, you can execute the system’s frequent testing to see how the workload responds to change, allowing you to plan ahead. Virtual and automated resources make this flexibility possible.

● Understand Cloud Consumption
Having a working knowledge of how cloud content is consumed will help you make more informed decisions that don’t compromise efficiency. When you have knowledge of certain system aspects, you can apply that to your selections to increase storage capability or network function.

The AWS Well-Architected Framework’s first pillar, Operational Excellence, is all about ensuring your company runs optimally. To accomplish operational excellence, you can follow the four designated best practice areas of this pillar, organisation, prepare, operate, and evolve.

The first best practice area, organisation, is critical for Operational Excellence because having an organised system makes it easier to identify and solve problems and allows your team to work together seamlessly.

Organisation Helps Your Team Work Better
Knowing exactly what they should be doing at all times helps your team remain consistent and excel at their jobs. Without an organised structure, your team may not know what to do without asking a supervisor, slowing down their pace.

You can also benefit from organised goals. If your team knows your daily, weekly, monthly, and yearly goals, they can alert someone if they notice your output falling behind. Additionally, knowing the goals can empower your team to work harder.

Having an organised plan for emergencies can help reduce the damage since you won’t need to spend time devising a way to deal with the problem. If you follow the organisation best practice, your team should know the process for dealing with most contingencies. Ensure you create contingency plans for a variety of problems, including physical ones like a fire in the building or loss of electricity, and virtual ones, like a hacking attempt or a virus in your system.

Ensures You Meet All Regulations
Another significant benefit of following organisational best practices is that you minimise your chances of missing an important deadline or failing to fulfil an industry regulation. Some industries have extensive regulations, from reporting requirements to maintaining certain standards.

Particularly if you operate across national borders, remembering and following all the necessary regulations is challenging. Having an organised structure that tracks deadlines and requirements is essential to keeping your company’s practice aligned with legal requirements. Additionally, you can organise a structure that continues to check for any changes in regulations that could affect your operations.

How AWS Can Help you Deliver the Best Value for the Lowest Price Point

The AWS Well-Architected Framework is designed to give you a consistent way to apply design and architectures that can evolve with you and your organisation. Through the use of five pillars, AWS is dedicated to maximising efficiency and keeping your costs at a minimum so your business can perform at its best.

Five Pillars of AWS and Your Money
The five pillars of AWS are designed to give you the best value for your money. They are a solid foundation that allows for stable growth as you build your cloud-based system. Cost optimisation is the pillar founded on ensuring you get back what you put into AWS.

Operational excellence refers to supporting the development and running workloads with efficiency. Operation can be optimised through organisation, preparation, and evolution of the system once mistakes are recognised.

Security requires that we protect assets, systems, and information in the cloud. With real-time detection, infrastructure and data protection, and incident response, you can solve security problems before impacting your clients. Investing in security now will save you time and money later.

Reliability is vital to maintaining the lowest possible costs. With a workload performing its function correctly, as expected, it is easy to anticipate values that will come in and go out. The workload needs to evolve and self-repair when failure is detected to maximise its value.

As demands change and evolve, your performance efficiency must adapt too. Understanding the computing resources available and using them in a way that best meets system requirements is a concrete way to receive back the value that you are putting into AWS.

Cost optimisation is the main area where you can ensure you receive the best value for the lowest price point with AWS.

Cost Optimisation
There are five best practices for cost optimisation with AWS that will assist in maximising your costs. Practising Cloud Financial Management, being aware of expenditure and usage, using cost-effective resources, managing demand, and supply resources, and optimising over time are the actions that should be taken for cost optimisation to be successful.

Cost-effective resources have a positive economic impact and can reduce overhead costs through their efficiency. Moving to the cloud, you are only incurring the necessary expenses. By tailoring your resources to match the workload, you are eliminating the tendency for wasteful spending.

Reviewing your architecture over time allows you to optimise continually. The cloud is ever-changing, and there are always new technologies to examine and see how they align with your own needs.
