Category: Solution architecture framework

Creating a software system is a lot like constructing a building. If the foundation is not solid, structural problems can undermine the integrity and function of the building. When architecting technology solutions on Amazon Web Services AWSif you neglect the five pillars of operational excellence, security, reliability, performance efficiency, and cost optimization, it can become challenging to build a system that delivers on your expectations and requirements. Incorporating these pillars into your architecture helps produce stable and efficient systems.

This allows you to focus on the other aspects of design, such as functional requirements. The AWS Well-Architected Framework helps cloud architects build the most secure, high-performing, resilient, and efficient infrastructure possible for their applications.

The framework provides a consistent approach for customers and AWS Partner Network APN Partners to evaluate architectures, and provides guidance to implement designs that scale with your application needs over time. The Operational Excellence pillar includes the ability to support development and run workloads effectively, gain insight into their operation, and continuously improve supporting processes and procedures to delivery business value.

You can find prescriptive guidance on implementation in the Operational Excellence Pillar whitepaper.

Solution Architect: Processes, Role Description, Responsibilities, and Certifications

Operations teams need to understand their business and customer needs so they can support business outcomes. Ops creates and uses procedures to respond to operational events, and validates their effectiveness to support business needs.

Ops also collects metrics that are used to measure the achievement of desired business outcomes. Everything continues to change—your business context, business priorities, customer needs, etc. The Security pillar includes the ability to protect data, systems, and assets to take advantage of cloud technologies to improve your security. You can find prescriptive guidance on implementation in the Security Pillar whitepaper. Before you architect any workload, you need to put in place practices that influence security.

In addition, you want to be able to identify security incidents, protect your systems and services, and maintain the confidentiality and integrity of data through data protection. You should have a well-defined and practiced process for responding to security incidents.

These tools and techniques are important because they support objectives such as preventing financial loss or complying with regulatory obligations. The AWS Shared Responsibility Model enables organizations that adopt the cloud to achieve their security and compliance goals.

Because AWS physically secures the infrastructure that supports our cloud services, as an AWS customer you can focus on using services to accomplish your goals.Generally, IT companies go about creating a detailed design of the solution as soon as they get the requirement document.

It is ignored by the consultants as they fail to understand the importance of a Solution Architecture. It leaves them with an unclear scope of project and this creates confusion in estimation, communication and also hurdles in the development process. In the long run, it can greatly affect the end results of the project and lead to waste of time and resources.

Here, in this blog we are going to not only highlight the importance of a Solution Architecture but also discuss the approach of building one step by step. At Helios, we make sure we follow our philosophy where we give high importance to solution architecture.

solution architecture framework

As according to our philosophy, not having solution architecture for software solution can be a big loophole in the overall development process. Solution architecture is the detailed and structured description of the features, process and behavior of the solution. It acts as the base of the solution to define, deliver, manage and operate the development process of the solution.

It identifies the alternatives of the solutions and its components. It is a basic architecture of the offered solution. Now, in the contemporary times, it is the practice that Solutions Architect prepares with the help of the consultants, project managers and the developers. The solution architect defines the relationship of the process internally and to the environment by considering the principles of design and keeping the scope of evolution in mind.

It is meant to support, automate and adapt to the business ideas and goals. Of course, like any other document, we start with the introduction of the software solution. This document should include the purpose, glossary, background, assumptions, references and other important information. Also, including the methodologies is also important.

Make sure that you state the scope of the document clearly where it should be convincing to the client that the document incorporates all the requirements of the solution. This part of the document should state the business goals and the solutions goals.

The 5 Pillars of the AWS Well-Architected Framework

The technical writer shall draft the purpose of building this architecture along with the vision that it wishes to fulfill. This content could also include the constraints that the project can expect to have. So the stakeholders are well aware and prepared for the mentioned constraints. Moreover, this could be helpful for the developers too. Mention the standards of methodologies that the developers will be using to develop the solution.

This part of the document must clearly highlight the quality attributes of the system like the performance, scalability and compatibility. This part of the document will comprise the model that will detect the key pointers of the software solution. Basically what it will take to prepare and develop this solution. Try to use cases, diagrams of Use Case etc. The logical view is nothing but a chronological structure that offers the breakdown of the requirements of the system.

Like the various stages, packages and steps in the process of development. This will help the developers and the stakeholder to have clarity on the system requirements.A typical property of Solution Architecture, in contrast to other flavours of Enterprise Architecture, is that it often seeks to define a solution within the context of a project or initiative. According to Forrester ResearchSolution Architecture is one of the key components by which Enterprise Architecture delivers value to the organization.

It entails artifacts such as; solution business context, solution vision and requirements, solution options e. Since The Open Group does not recognize a unique Solution Architect role a relevant link for these mentioned artifacts can be to the Business and Systems Analyst roles.

It is also worth reminding that The Open Group does define Solution Architecture as something larger than Forrester see aforementioned definition.

Then on, according to the paper published by the Federation of Enterprise Architecture Professional OrganizationsSolution Architecture includes business architectureinformation architectureapplication architectureand technology architecture operating at a tactical level and focusing on the scope and span of a selected business problem. In contrast, enterprise architecture, which also includes the aforementioned four types of architecture, operates at the strategic level and its scope and span is the enterprise rather than a specific business problem.

The framework consists of five pillars of architecture excellence: Cost Optimization, Operational Excellence, Performance Efficiency, Reliability, and Security. When you are designing a cloud solution, focus on generating incremental value early. Apply the principles of Build-Measure-Learnto accelerate your time to market while avoiding capital-intensive solutions.

Use the pay-as-you-go strategy for your architecture, and invest in scaling out, rather than delivering a large investment first version. Consider opportunity costs in your architecture, and the balance between first mover advantage versus "fast follow". Use the cost calculators to estimate the initial cost and operational costs. Finally, establish policies, budgets, and controls that set cost limits for your solution. This pillar covers the operations processes that keep an application running in production.

Deployments must be reliable and predictable. They should be automated to reduce the chance of human error. They should be a fast and routine process, so they don't slow down the release of new features or bug fixes. Equally important, you must be able to quickly roll back or roll forward if an update has problems. Monitoring and diagnostics are crucial. Cloud applications run in a remote data-center where you do not have full control of the infrastructure or, in some cases, the operating system.

In a large application, it's not practical to log into VMs to troubleshoot an issue or sift through log files. With PaaS services, there may not even be a dedicated VM to log into. Monitoring and diagnostics give insight into the system, so that you know when and where failures occur. All systems must be observable. Use a common and consistent logging schema that lets you correlate events across systems.Physical and cloud servers, applications, and enterprise software all must communicate and share data seamlessly in order to provide the customer a successful and satisfactory user experience.

The holistic view of all these pieces is referred to as enterprise architecture. Guidance surrounding this implementation are often known as enterprise architecture frameworks EAFswhich we are exploring from a high level in this article.

Simply stated, enterprise architecture framework EAF refers to any framework, process, or methodology which informs how to create and use an enterprise architecture.

Solution Architecture Essentials

At a high level, enterprise architecture offers a comprehensive approach and holistic view of IT throughout an enterprise. This can also include any organized unit that has a common goal, such as an industry consortium or non-profit group. An enterprise requires collaboration to achieve its goal or strategy while providing the good or service as best as it can to ensure customer satisfaction.

While no single definition of enterprise architecture exists, it is understood as a practice or discipline of organizing logic that promotes a health IT infrastructure that makes sense for successful business practices. The process should convert intangible business strategy to practical, real solutions that can be measured and achieved.

Relying on the practices of architecture, enterprises can analyze, design, plan, and implement the technology they need to execute their business strategies.

The architecture should also incorporate 21 st century practices of business process management and data analytics. Across the many frameworks that serve to achieve an enterprise architecture, the goal of the comprehensive approach is always to successfully execute strategy with efficiency, efficacy, security, durability, and agility.

A commonly held tenet is that enterprise architecture frameworks date to the mids, in accordance with the publication of the Zachman Framework, developed by then-IBMer John Zachman. But deeper historic inquiries indicate that enterprise architecture frameworks actually got their start two decades earlier, when IBM produced their business systems planning BSPan effort that Zachman helped found.

A researcher of 20 th — and 21 st -century technology, Svyatoslav Kotusev says that we can look at the history of EAFs in three smaller eras :. Despite the differences in approaches that these eras indicate, all frameworks are generally based on the original BSP methodology, often advocating similar steps or phases for planning and implementing enterprise IT.

Some enterprises look to adopt service-oriented architecture SOA or microservices architecture MSA often a key component of establishing a digital transformation which has an impact on both IT and business processes.

These may be the best candidates for enterprise architecture. At its most helpful, an enterprise architecture framework makes sense of the complexities of achieving business strategy via IT strategytechnology, and business needs across all silos of the company. When performed at its best, an enterprise architecture translates the vague and intangible business strategy to practical, concrete plans and actions.

Then, these designs are translated into solutions that achieve business strategy. Other benefits include improved agility within the business.

By aligning business needs across all silos, companies can visualize actual business motives and drivers. The blueprint that accompanies enterprise architecture allows the company to understand how all the business IT pieces fit together, which can result in better systems maintenance and support as well as IT management.

Ultimately, successful enterprise architecture leads to better planning and change management — budgets are set, system interoperability is double-checked, and various employee roles can see into the system, offering a common vocabulary that can improve and enhance communication across business needs.

The types of enterprise architecture frameworks are often categorized by who created and released them. A company looking for the right EAF must know that these frameworks vary widelywith some providing more structure around the taxonomy, classification, or organization of an enterprise. On the other hand, others emphasize process.

As some experts point out, EAFs can vary from processes or full-blown methodologies to more flexible practices. In certain comparisons, EAFs are very similar and repetitive, and others have little in common beyond the name of enterprise architecture framework.

Historically, the frameworks tend to offer similar processes to follow when implementing an enterprise architecture, yet there were some problems with these so-called solutions:. Still, maintaining the documentation is often too cumbersome and time consuming.The design and communication of high-level structures to enable and guide the design and development of integrated solutions that meet current and future business needs.

In addition to technology components, solution architecture encompasses changes to service, process, organisation, and operating models. The provision of comprehensive guidance on the development of, and modifications to, solution components to ensure that they take account of relevant architectures, strategies, policies, standards and practices including security and that existing and planned solution components remain compatible.

Leads the development of architectures for complex solutions, ensuring consistency with specified requirements agreed with both external, and internal customers. Takes full responsibility for the balance between functional, service quality and systems management requirements within a significant area of the organisation. Establishes policy and strategy for the selection of solution architecture components, and co-ordinates design activities, promoting the discipline to ensure consistency.

Ensures that appropriate standards corporate, industry, national and international are adhered to. Within a business change programme, manages the target design, policies and standards, working proactively to maintain a stable, viable architecture and ensure consistency of design across projects within the programme. Leads the development of solution architectures in specific business, infrastructure or functional areas. Ensures that appropriate tools and methods are available, understood and employed in architecture development.

Within a change programme, leads the preparation of technical plans and, in liaison with business assurance and project staff, ensures that appropriate technical resources are made available. Provides advice on technical aspects of solution development and integration including requests for changes, deviations from specifications, etc.

Contributes to the development of solution architectures in specific business, infrastructure or functional areas. Identifies and evaluates alternative architectures and the trade-offs in cost, performance and scalability. Produces specifications of cloud-based or on-premises components, tiers and interfaces, for translation into detailed designs using selected services and products. Supports a change programme or project through the preparation of technical plans and application of design principles that comply with enterprise and solution architecture standards including security.
