Was sind die Best Practices für die Entwicklung eines Hybrid-Cloud-Servicemodells?

Some of the design principles and best practices that we can consider for hybrid cloud model (0) Perform Data Center Assessment (1) Design for Secure Data Exchange (2) Consider Modernization Strategy (3) Use Unified Tools for Orchestration, CICD Pipeline, Logging & Monitoring, Security purpose (4) Adopt Right API gateway and service mesh (5) Establish Governance Model

As per my experience below are the some of the best practices - Policy management and enforcement - Enforce Security in each and every layer - System security and its effect on performance

Agility, Scalability, Resilience, Security, and Compliance definitely answers the benefits of cloud but is that all what your organization aims for? And this brings us to define the objectives of a hybrid cloud service model where the organization might be running legacy applications which might not run on cloud in it's as-is state and would require a lot of code re-write to make it cloud ready, or there might be scenarios where a compliance regulation restricts certain class of data to be moved across geographies. The public cloud has matured to a great extent in terms providing everything required to run an enterprise (technically), but it all boils down to each organization's requirement to keep something local vs going all out on cloud.

In my experience working across the entire U.S both at Google and at VARS... I like to make sure we ask the right questions of "Why" we are pursuing hybrid and multi-cloud as well as make sure we are properly architected prior to adding in more technologies to your tech stack.

Best practices for designing a hybrid cloud service model include: 1) Assessing and aligning with business needs. 2) Ensuring compliance and security protocols. 3) Implementing robust data management and governance. 4) Optimizing workload distribution between private and public clouds. 5) Integrating cloud management platforms for unified control. 6) Planning for scalability and flexibility. 7) Focusing on interoperability and API integration. 8) Regularly reviewing and updating the architecture based on evolving requirements. 9) Implement FinOps to retain control over your cloud cost and AIOps to maintain control over your multi cloud environments performance.

When assessing consider the 7Rs of a migration: -Rehosting: Referred as a ‘lift & shift’ approach. Take your infrastructure as it runs now and move it to the cloud with minimal changes -Re-platforming: Utilise managed services offered by the vendor -Repurchasing: Repurchase the same or similar applications in the cloud to perform the same operations -Refactor: Time consuming and costly, but allows you to take full advantage of the benefits of your cloud vendor -Relocating: A lift and shift approach at the hypervisor level, specific to workloads running a vSphere-based environment (VMware on AWS) -Retiring: Remove services that do not provide any real value to you as a business -Retaining: Identify which services should remain on-premises

It involves evaluating the characteristics, dependencies, and requirements of existing or planned applications and services. This assessment helps determine which workloads are suitable for on-premises or public cloud deployment. Factors like performance, scalability, data sensitivity, compliance, and cost are considered. It enables informed decision-making on workload placement and migration strategies, ensuring optimal resource allocation and integration. Workloads are evaluated for compatibility with hybrid cloud management tools, and architectural changes may be made to adapt them. Overall, workload assessment ensures the successful deployment and operation of applications and services within a hybrid cloud environment.

In time's of Hybrid Cloud model, their is no one size that fits all. Based on the use case, we need to choose the relevant CSP's and the relevant value preposition it is providing against the respective workload.

Choosing cloud providers in designing a hybrid cloud service model involves selecting the public cloud platforms that best meet the organization's requirements. Factors to consider include service offerings, performance, scalability, security, compliance, cost, and integration capabilities. Evaluating providers helps optimize workload placement, leverage specialized services, and ensure seamless integration and interoperability across the hybrid cloud environment. It enables organizations to leverage the strengths of different cloud providers while maximizing the benefits of a hybrid cloud architecture.

The description given on the left basically sums it up on what it entails to take the drawing board and come up with an architecture for a cloud environment. Double-clicking on couple of keywords mentioned and highlighting the factors to be in kept in mind while architecting: - Avoiding single point of failures (resiliency) - Avoiding bottlenecks (performance) - Being Compliant (Data is gold) - Tiered security and governance - Least privilege access - Automation and operational efficiency (IaC, tooling, etc.) - and COST (you can throw in all sorts of goodies in terms of defining "the architecture", but choosing the right SKUs of cloud services as per business need is the bottomline of well-architected design.

It involves creating a blueprint that combines on-premises infrastructure with public cloud resources. It begins by identifying the components and their interconnections, such as networking, storage, compute, and security. The architecture should leverage the strengths of each environment, considering factors like workload placement, data synchronization, and application integration. Hybrid cloud management tools enable centralized control and monitoring across environments. Strategies like bursting, disaster recovery, and data backup are implemented to optimize resource utilization and ensure business continuity. Security measures, such as encryption and access controls, are designed to protect data in transit and at rest.

The more time you spend in sharpen your axes, the greater benefit you can leverage. If the assessment and solutioning for Hybrid environment is done in a right way, implementation will be easy and fruitful. Using the right stratedgy and tools are key for implementing complex migrations.

It Involves executing the designed architecture and deploying the necessary components. It begins by configuring the on-premises infrastructure, including networking, storage, and compute resources. Integration with public cloud services is established, ensuring connectivity and data synchronization between environments. Workloads are deployed, either on-premises or in the public cloud, based on their requirements and placement decisions. Hybrid cloud management tools are implemented to enable centralized monitoring, provisioning, and management of resources. Automation and orchestration are leveraged to streamline operations and ensure consistency.

Planning for seamless integration between on-premises and cloud environments is one of many things people tend to overlook. Use APIs, hybrid cloud management tools, and identity management solutions for best results.
