Cloud-first Architecture Strategy

In a recent blog, I explained how you can write an Architecture Strategy. It’s easy to put a template, but it’s quite to put that template to use. So, I decided to eat my own dog food by following the template and creating an Architecture Strategy.

In the blog, I also gave a few examples of Architecture Strategies that you can write. In those examples, the first one was Cloud-first Architecture Strategy. So, with a bit of fiction (in real scenarios aspects like the current state can only be created when you are doing this for an organization), I am going to attempt creating an architecture strategy for Cloud-first for an enterprise/organization and how it will look like.

As I mentioned, in some sections of the document, I would give you mechanisms to arrive at the content which can be put in and how we can represent those. So, let’s dive deep into creating our cloud-first architecture strategy.

Please note, I don’t want this blog to be spanning many pages, so I will be crisp in certain places. It will try to give a good amount of details but wouldn’t be explained in all aspects. If you feel you need more details, please comment and I will see if I can write a follow-up blog on this topic that is more detailed.

Introduction

This section should provide an overview of the document and explain the purpose of the “cloud-first” architecture strategy, including how it aligns with the enterprise’s business goals and objectives (e.g. increasing agility and scalability, reducing costs).

The purpose of this document is to outline a “cloud-first” architecture strategy for [Enterprise name]. The strategy focuses on leveraging cloud-based technologies and platforms to improve the agility and scalability of the enterprise’s technology systems, while also reducing costs. The strategy aligns with the enterprise’s business goals and objectives of increasing the speed of deploying new features and capabilities, reducing IT costs and improving scalability.

The “cloud-first” architecture strategy is designed to address the challenges of the traditional on-premises infrastructure and to take advantage of the benefits of the cloud. The strategy lays out a roadmap for migrating the majority of systems and applications to the cloud and outlines a governance model to ensure that the strategy is implemented effectively and consistently across the enterprise.

This document will provide an overview of the current state of the enterprise’s technology architecture, describe the desired future state, and outline the steps that will be taken to move from the current state to the target state. It will also identify any key risks or challenges that may arise and describe how they will be addressed. By implementing this “cloud-first” architecture strategy, the enterprise will be able to increase its agility, reduce costs, increase efficiency, and enhance its ability to innovate.

Business Goals and Objectives

This section should outline the key business goals and objectives that the “cloud-first” architecture strategy is intended to support, such as increasing the speed of deploying new features and capabilities, reducing IT costs, and improving scalability.

The “cloud-first” architecture strategy is designed to support the following key business goals and objectives:

  • Increase the speed of deploying new features and capabilities: By leveraging the agility and scalability of cloud-based technologies and platforms, the enterprise will be able to deploy new features and capabilities at a faster rate, allowing it to respond more quickly to changing market conditions and customer needs.
  • Reduce IT costs: By moving systems and applications to the cloud, the enterprise will be able to reduce the costs associated with maintaining and upgrading on-premises infrastructure.
  • Improve scalability: Cloud-based technologies and platforms are designed to be highly scalable, allowing the enterprise to quickly and easily add capacity as needed. This will enable the enterprise to respond to increases in demand without incurring significant costs.
  • Enhance disaster recovery and business continuity: By using cloud-based technologies and platforms, the enterprise will be able to ensure that its systems and data are protected against disasters and other disruptions.
  • Increase security: Cloud-based technologies and platforms often provide built-in security features and are managed by security experts, which can help the enterprise to improve its overall security posture.
  • Meet regulatory compliance: Many cloud-based technologies and platforms are compliant with various regulations, which can help the enterprise to meet its compliance requirements.

Note: The “cloud-first” architecture strategy should be flexible enough to adapt to the changing business environment and technology landscape.

Current State Assessment

This section should provide a detailed analysis of the current state of the enterprise’s technology architecture, including an inventory of systems, technologies, and platforms in use, as well as any key challenges or constraints related to cloud adoption.

Since I don’t have an enterprise/organization, in this I will try to give you mechanisms to arrive at the current state assessment and how to represent those in your strategy document.

Some of the key elements that may be included in a current state assessment for a “cloud-first” architecture strategy include:

  1. Inventory of systems and applications: A comprehensive inventory of all the systems and applications currently in use by the organization, including their purpose, location, and dependencies.
  2. Cloud readiness assessment: An analysis of the current systems and applications to determine their readiness for migration to the cloud, including their ability to run in a virtualized environment and their compliance with cloud security and regulatory requirements.
  3. Cost analysis: An analysis of the costs associated with maintaining the current systems and applications, including hardware and software costs, maintenance and support costs, and personnel costs.
  4. Performance analysis: An analysis of the performance of the current systems and applications, including response time, throughput, and availability.
  5. Scalability analysis: An analysis of the scalability of the current systems and applications, including the ability to handle increased load and the ability to add new users or devices.
  6. Security analysis: An analysis of the security of the current systems and applications, including an assessment of the risk of data breaches and the effectiveness of security controls.
  7. Data analysis: An analysis of the data used by the current systems and applications, including an assessment of data storage, data access, and data security.
  8. Dependency analysis: An analysis of the dependencies between the current systems and applications, including an assessment of the impact of migration to the cloud on those dependencies.

The results of the current state assessment should be represented in a clear and concise manner, such as using diagrams, tables, or matrices. This can include a representation of the current systems and technologies in use, their dependencies, and the complexity of the current architecture. It can also include an analysis of the current security posture, compliance status, and disaster recovery capabilities. It is important to include any known technical constraints or challenges that may impact the ability to implement the “cloud-first” architecture strategy.

Note: Once the current state assessment is complete, the enterprise should have a clear understanding of the current state of its technology architecture and any challenges or constraints that may impact the ability to implement the “cloud-first” architecture strategy. This will provide a solid foundation for creating the target state vision and roadmap.

There are several ways to represent the results of a current state assessment in a clear and concise manner. Some common methods include:

  1. Architecture diagrams: These diagrams provide a high-level view of the current state of the enterprise’s technology architecture, showing the relationships between different systems, technologies, and platforms. They can include elements such as servers, networks, applications, and data stores.
  2. System inventory: This can be a spreadsheet or table that lists all of the systems, technologies, and platforms currently in use by the enterprise, along with information such as vendor, support status, and age. This can also include the number of instances, the location, and the usage of each system.
  3. Matrices: Matrices can be used to show the relationship between different systems, technologies, and platforms, as well as their characteristics such as vendor, support status, and age. They can also be used to show the relationship between systems and the business processes they support.
  4. Technical assessment report: This report covers the technical aspects of the current state assessment, including the results of technical assessments such as penetration tests, load tests, and vulnerability scans.
  5. Compliance and security report: This report covers the current compliance status of the enterprise, including any regulations or standards that the enterprise must comply with, as well as the current security posture of the enterprise.
  6. Flowcharts: Flowcharts can be used to show the flow of data and information between different systems and technologies, as well as to depict the current business processes and how they are supported by the current technology architecture.
  7. Dashboards: This can be a visual representation of the current state assessment, providing a high-level overview of the enterprise’s technology architecture, and showing the key metrics and indicators related to the current state of the enterprise’s technology.

Note: The representation method chosen should be tailored to the specific context of the enterprise, and should be easily understandable by the intended audience. It’s also important to choose a representation that is easy to update and maintain as the architecture evolves. For example, an enterprise with a complex and large IT environment may require a more detailed representation, such as a detailed system inventory or an interactive dashboard that provides a real-time view of the current state. On the other hand, a smaller enterprise may require a simpler representation, such as a high-level architecture diagram.

Target State Vision

This section should describe the desired future state of the enterprise’s technology architecture, including a detailed plan for moving the majority of systems and applications to the cloud, and identifying key systems and applications that may not be suitable for migration.

The target state vision includes the following key elements:

  • Cloud-based infrastructure: The majority of the enterprise’s systems and applications will be hosted on cloud-based infrastructure, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP). This will provide the enterprise with the flexibility and scalability it needs to respond quickly to changes in demand.
  • Cloud-native applications: The enterprise will develop and deploy new applications using cloud-native technologies and patterns, such as microservices, containers, and serverless computing. This will enable the enterprise to take full advantage of the scalability and automation capabilities of the cloud.
  • Hybrid cloud: For systems and applications that cannot be moved to the cloud, the enterprise will implement a hybrid cloud architecture that allows for the integration of on-premises and cloud-based infrastructure.
  • Governance: The enterprise will implement a governance model to ensure that the “cloud-first” architecture strategy is implemented effectively and consistently across the enterprise. This will include roles, responsibilities, decision-making processes, and guidelines for cloud usage and security.
  • Security: The enterprise will implement robust security measures to protect its systems and data in the cloud. This will include measures such as encryption, multi-factor authentication, and network segmentation.
  • Compliance: The enterprise will ensure that its use of cloud-based technologies and platforms is compliant with all relevant regulations and standards.

Similar to “Current State Assessment”, this section can use the same mechanisms to represent.

Roadmap
