AWS Well-Architected Review: Optimal Cloud Architecture

One cloud, thousands of options! But with all the benefits and options that cloud applications offer, companies should never lose sight of two things: Security and efficiency. It is therefore important to have a thought-out cloud architecture that takes into account all conditions and requirements as well as common best practices. This is where the AWS Well-Architected Framework comes in. It was specifically designed to help cloud architects develop fail-safe, high-performance and efficient infrastructures for their applications.
Today's Amazon Web Services (AWS) offer enterprises a wide range of opportunities - and at the same time present them with a number of challenges: How can we get the most out of cloud migrations? What is the best way to deal with cloud-native application architectures? With these and other considerations in mind, there is often a risk that security requirements will not be sufficiently taken into account and that high costs may arise. After all, the secure and reliable operation of applications has long been essential for companies. Many applications are business-critical and can lead to high financial losses if they fail.

Accurate analysis, fast improvement

Together with AWS, T-Systems offers a tailor-made solution: The Well-Architected Review. This solution closely examines and improves existing cloud architectures. For this purpose, all existing applications are analyzed in detail. This provides companies with valuable insights into their current application status. Based on the individual analysis and evaluation by T-Systems experts, immediate improvement measures can be implemented that lead to more control and lower risks. For the reviews, T-Systems works very closely with the application managers and reviews their needs. Hence, the redesign of the architecture always takes the most important security, availability and efficiency components into account.

Joint kick-off workshop

In practice, experienced and certified T-Systems architects conduct a joint workshop to precisely analyze the company's existing architecture and determine initial optimization measures. The framework for evaluating the architecture is based on AWS Best Practices for the design and operation of cloud-based applications, the so-called AWS Well-Architected Framework.
This framework consists of five principles:
Pillars of the Well-Architected Reviews
This pillar focuses on optimizing operations and monitoring systems. The objective is to continuously increase the amount of value added by optimizing structures, processes, and workflows.
Protecting data and systems has the highest priority. This includes measures to protect privacy and data integrity, for instance by implementing appropriate access controls or using monitoring to detect security breaches.
By avoiding errors and establishing rapid, automated system restoration procedures in the event an application goes down, high availability is achieved. The architecture is designed to detect resource bottlenecks and request additional capacity. Avoiding downtime that results from improper configurations and temporary network errors. Corresponding measures as necessary include automated scaling, backup, recovery, and managing modifications.
Optimized use of AWS resources, even during periods of fluctuating demand or varying system requirements and technologies—specifically, selecting the right services and resource types while taking modern architecture paradigms into consideration such as serverless architectures.
Comprehensive analysis and adaptation of resource consumption to avoid and reduce unnecessary costs. Capacity reservation and resource optimization are potential measures here.

Customer benefit:

Companies that opt for an AWS Well-Architected Review from T-Systems can use cloud environments and functions as effectively and efficiently as possible. They can scale their applications flexibly and at the same time fulfill all important security aspects. The concrete added value is:
  • Faster development and deployment of applications
  • Mimimized risk
  • Sound decisions
  • Insights from AWS Best Practices
  • An evaluation by an independent third party
  • A plan for continuous improvement

This is how an AWS Well-Architected Review is conducted by T-Systems:

In an initial telephone consultation, the application to be reviewed is selected. Here, the customer's questions are also answered, and the further framework conditions discussed.
It makes sense for the review to take place on site – This makes it easier for the company's technical experts and application managers to attend. The selected application is presented during the review. The application purpose, architecture and requirements are considered and discussed in detail analogous to the five principles of the AWS Well-Architected Framework. Usually 4-5 hours are estimated for this stock-taking phase.
In the second step, the actual work of the AWS experts at T-Systems begins: The results are evaluated, and concrete improvement measures are developed. The customer then receives a non-binding proposal for a roadmap to implement the medium- and long-term objectives.
Finally, the company itself is in demand. This is because the customer decides on the concrete implementation and the corresponding timetable. The AWS experts are happy to provide service credits (on request) to support the implementation of the optimal cloud architecture with T-Systems.
