    Why You Need a Multi-Cloud Strategy for Application Modernization

    2 Minutes read

More than 90% of enterprises use the cloud, yet a single provider of cloud services for business fails to cover the needs of an organization entirely. There is a considerable need for flexibility, agility, customization, reliability, operations, and security, and these needs cannot be fulfilled with a single or one-size-fits-all cloud strategy. This is where enterprises should take a multi-cloud approach. As a business, you can modernize legacy IT applications with a multi-cloud strategy without any limitations of the single cloud.

What is Multi-Cloud Strategy?

Multi-cloud may be defined as the presence of more than one cloud deployment of the same type, private or public, sourced from the many vendors. This approach could involve two public or two private cloud environments. The multi-cloud strategy enables you to benefit from new and specialized platform-as-a-service(PaaS) offerings and integrates them with best-of-breed clouds for legacy IT applications. Thus, your enterprise can move forward with modern infrastructure, architectures, and processes for all types of applications, whether traditional or modern.

Data suggests almost 80% of companies have undergone multi-cloud implementations. The multi-cloud approach uses multifarious cloud service providers, offering a unique service among a broader set of customer needs. As you modernize your legacy IT applications, this is what you should consider in your provider of cloud services for businesses.

Considerations for Legacy App Modernization Using Multi-Cloud

1. Provider Focus

It refers to the purpose-built to modernize legacy applications in the cloud. Most of the applications running in on-premises data centers are a combination of physical and virtual systems. Virtual applications are ideal for migration to the cloud. Note that the holistic enterprise’s legacy application portfolio is complex and broad, requiring you to address mainframes, IBM. I pars for AIX, bare metal, and Linux. Choose a vendor that allows for a mix of legacy and modern enterprise architecture and operating systems. It should support new approaches of containers and microservices for further modernization of your architecture.

2. Migration

Legacy IT applications were built on the notion that they would run inside a private data center. The more changes the target cloud needs to make to the application, the more rework should be done to migrate it. Cloud design and networking should reflect the current environment of legacy applications as closely as possible. Doing so helps to minimize the changes. Your provider of cloud services for business should have the ability to get relatively low in the networking stack to ensure capturing all configurations.

With a multi-cloud strategy in place, organizations can benefit from new, specialized, or best-of-breed PaaS offerings. They integrate those with best-of-breed clouds for legacy applications, finally moving the organization forward with modern infrastructure, architectures, and processes for all applications.

3. Choice of Multi-cloud

Do you rely on a single provider to serve all your application requirements? Most platform-as-a-service (PaaS) providers try to convince you that their infrastructure-as-a-service (IaaS) offer can solve the needs of legacy IT applications. Once the IaaS offer falls short, these providers encourage the business to embark on rearchitecting or rewriting PaaS. Opting for a single provider offering cloud services for business risks your capability to leverage best-of-breed cloud-native services while settling for just enough.

4. Management of Costs

Migrating to the cloud should not lead to substantial cost overruns. Some solutions offer predictive calculators for forecasted spending or reactive reporting of usage patterns to help detect costs instead of managing them from the beginning. Schedules, quotas, notifications, auto-suspend, and alerts actively take care of costs but are unavailable in every solution. It would help if you considered how you need to avoid overruns before they happen.

5. Complexity

Typically, providers of cloud services for businesses have various infrastructure services that should be configured before the application can run in the cloud. This brings about a level of unanticipated complexity and increased learning curve as your staff boosts each service. The approach makes it challenging for testers and developers who are unfamiliar with the details of the infrastructure. Providers of cloud services for businesses that can extract the underlying infrastructure configuration enable teams to adopt and benefit from the cloud faster.

6. Choice of Deployment

It would help if you understood that legacy applications have varied requirements. Flexibility to determine how the application is deployed in the cloud can make or break that application. Generally, cloud service providers run on multitenant shared infrastructure, while others offer dedicated tenants, bare metal options, and regions to accommodate the dynamic application needs.

7. Usability

The modernized solution should be easy for Dev, IT, and QA organizations to adopt, necessitating little to no new conceptual learning or skills. The legacy application’s software development life cycle (SDLC) should be able to keep pace with that of modernized applications. The speed of innovation increases radically if a user can provision QA, development, and other environments on their own. To eliminate environmental constraints and modernize applications faster, offering self-serve application environments will remove configuration drift, significantly mitigating provisioning times throughout the SDLC.

More than 30% of customers are connecting to external cloud services to create multi-cloud applications.

Are You Ready to Modernize with a Multi-Cloud Strategy in Place?

Our holistic understanding of enterprise cloud computing across the industry continues to evolve. The evolution clearly shows choosing a single-cloud strategy confines organizations to a “one-size-fits-all” solution, which leads to long, complex, and costly failures. As best practices for cloud computing, organizations should embrace a multi-cloud strategy. There are cloud transformation services providers that help you with legacy app modernization in a multi-cloud environment.
