*The migration of applications from an on-premises environment to a cloud, with minor changes that leverage some of the cloud platform’s functionality such as autoscaling and high availability

Custom applications often represent heavy support burdensfor IT sta�. Issues may be compounded by lack of personnel skilled in an application’s specific architecture and infrastructure and by capacity constraints in on-premises datacenters.

Integration into legacy app environments remains the toptechnology bottleneck in the application delivery pipeline. Moving applications to the cloud and application modernization can resolve many challenges.

Multiple environments and tool stacks can inhibit DevOps scalability.

Modernizing while dealing with legacy applications is a formidable challenge.

Clouds also scale by expanding or contracting bandwidth as workloads require.

Plus the ability to meet changing market needs with favorable economics, improved risk mitigation of disaster recovery, built-in compliance, more robust and easier security, and DevOps cloud services.

Public clouds o�er cost-e�ective services to meet custom applications’ needs for data, storage, disaster recovery, artificial intelligence, and edge computing.

Modern services such as APIs, microservices, containers, functions, and container orchestration frameworks are common elements of application architectures on the cloud.

These services are rendered more e�ectively in public cloud than they are on premises today.

More than 25% of U.S. organizations regularly use multiple modern services.

Only 10% are not using or are only in the consideration phasefor modern application services.

Relative to the total number of custom apps,a larger portion are being built and deployed as cloud native.

Requirements include:

Organizations are taking a selective approach to choosing a vendor for migrating custom applications and their workloads to the cloud.

DevOps teams are leaning into cloud-native developmentand expect continued momentum looking out to 2022 – although progress is likely impeded by the friction of maintaining existing legacy applications. Moving existing applications to the cloudcan overcome that friction.

Most customers use multiple clouds today

Partner ecosystem, available back-end services, costs, performance, service-level agreements, and optimizationfor specific workloads could also justify a movement from one cloud platform to another.

47% of worldwide customers using clouds for production-grade applications use between 3 and 4 vendors (43% for U.S.).

An important consideration with most enterprise custom applications is working with a cloud vendor that accommodates split architectures (i.e., across application and database services) and uses fast interconnects across those services.

**The re-architecting of applications to optimize their functionality for the cloud (e.g., transforming monolithic applications to microservices architectures using containers)
