In this blog we are going to discuss how we, Pletratech, have designed a cloud application using AWS Well-Architect framework for secure, salable application.
Software design is the process by which an architect creates a specification of a software artifact, intended to accomplish goals, using a set of primitive components and subject to constraints. It is the process of envisioning and defining software solutions to one or more sets of problem. One of the main components of software development is a software framework.
Software framework is an abstraction in which software providing generic functionality can selectively change by addition user-written code. It provides a standard way to build and deploy application and is universal, reusable software environment that provides particular functionality as part of a larger software platform to facilitate development of software application, products and solution.
We can categorize into three sections of the software designing these are as–
- Architectural Design
- High-level Design
- Detailed Design
1- Architectural Design: – This is the first level of the designing. Architectural design is the greatest summarize edition of the system. This determines to the software or application as a method with more elements collaborating with each. Generally, this is a designing level where the designers obtain the idea or thought of a suggested clarification domain or province
2- High-level Design: – This is the second level of the designing. The high-level design splits the theory or concept single entity-multiple components into less-abstracted prospect of modules and subsystems. And also represents their cooperation with each. Basically, the high-level design concentrates on how the system besides all of its element can be applied as modules. High level design concept identifies modular arrangement of all subsystems and also their connection and cooperation between them.
3- Detailed Design: – This is the third level of the designing. This is the level where the designing deals with the accomplishment part, which will be finally seen by the system. This level of designing is more elaborated as compared to previous modules design and implementations. In this level of design, we determine the logical structure of all previous modules.
Cloud computing architectures consist of front-end platforms called clients or cloud clients. These clients are servers, fat (or thick) clients, thin clients, zero clients, tablets and mobile devices that users directly interact with. These client platforms interact with the cloud data storage via an application (middle ware), via a web browser, or through a virtual session. Virtual sessions in particular require secure encryption algorithm frame working which spans the entire interface. AWS has published a “AWS Well-Architect Framework” whitepaper to guide to use AWS services while designing application on AWS.
AWS Well-Architected Framework
This Framework will help you to learn architectural best practices for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud. It provides a way to consistently measure your architectures against best practices and identify areas for improvement. Pletratech has years of experience architecting solutions across a wide variety of business verticals and use cases. We have helped design and review thousands of customers’ architectures. We have identified best practices and core strategies for architecting systems in the cloud based on our own experience. This document provides a set of foundational questions that allow you to understand if a specific architecture aligns well with cloud best practices. The framework provides a consistent approach to evaluating systems against the qualities you expect from modern cloud-based systems, and the remediation that would be required to achieve those qualities. As AWS continues to evolve, and we continue to learn more from working with our customers, we will continue to refine the definition of well-architected. This framework is intended for those in technology roles, such as chief technology officers (CTOs), architects, developers, and operations team members. It describes AWS best practices and strategies to use when designing and operating a cloud workload, and provides links to further implementation details and architectural patterns.
The AWS Well-Architected Tool (AWS WA Tool) is a service in the cloud that provides a consistent process for you to review and measure your architecture using the AWS Well-Architected Framework. The AWS WA Tool provides recommendations for making your workloads more reliable, secure, efficient, and cost-effective. AWS has created AWS Well-Architected Labs, which provides you with a repository of code and documentation to give you hands-on experience implementing best practices. We also have teamed up with select AWS Partner Network (APN) Partners, Pletratech is one of them, who are members of the AWS Well-Architected Partner program. Pletratech assist customers in architecting systems to take advantage of best practices in the cloud. We work with you on making architectural trade-offs as your designs evolve. As you deploy these systems into live environments, we learn how well these systems perform and the consequences of those trade-offs. AWS Well-Architected Framework provides a consistent set of best practices for customers and partners to evaluate architectures, and provides a set of questions you can use to evaluate how well an architecture is aligned to AWS best practices.
The AWS Well-Architected Framework is based on five pillars —
- operational excellence
- performance efficiency
- cost optimization.
Operational excellence: Operational Excellence is the execution of the business strategy more consistently and reliably than the competition. It provides ability to support development and run workloads effectively, gain insight into their operations and improve process and procedure consensually to deliver business value.
Security: Security is an important pillar of any application to protect data, systems and assets to take advantage of cloud technologies.
Reliability: This provides ability of workload to perform it’s intended to give expected accurate output with consistency. This includes ability to operate and test the workload through its lifecycle.
Performance Efficiency: it provides the ability to use computing resources efficiently to meet system requirements and to maintain that maintain efficiency as demand and technologies changes.
Cost optimization: Costing is an important factor of any application design as we have to make sure that our design is cost effective to fit into our client’s budget. A good well-planned design architecture run system to deliver business value at lowest cost without sacrificing performance.
