Multi-cloud framework for microservice-based applications

A system, comprising:

• a memory;
• and
• at least one processing device, coupled to the memory, operative to implement the following steps:
• maintaining a structural state of a multi-cloud application comprising a plurality of microservices hosted in at least two distinct cloud environments, wherein the at least two distinct cloud environments are provided by at least two different cloud providers and execute one or more of the microservices, wherein the structural state of the application is maintained over time and comprises, for each microservice, an indication of the cloud environment that hosts the respective microservice and an indication of one of a plurality of microservice technology types, wherein the plurality of microservice technology types comprises:
• a Container as a Service type and a Function as a Service type;
• obtaining a source code for each of the plurality of microservices of the multi-cloud application and deployment instructions for each of the distinct cloud environments;
• deploying the plurality of microservices of the multi-cloud application using the structural state of the multi-cloud application, the source code for each of the plurality of microservices and the deployment instructions for each of the distinct cloud environments;
• and
• migrating at least one of the plurality of microservices that is deployed on a first one of the at least two distinct cloud environments to a second one of the at least two distinct cloud environments, wherein at least another one of the plurality of microservices is maintained on the first one of the at least two distinct cloud environments, and wherein the at least one microservice is migrated from a first one of a plurality of microservice technology types to a second one of the plurality of microservice technology types.

A computer program product, comprising a non-transitory machine-readable storage medium having encoded therein executable code of one or more software programs, wherein the one or more software programs when executed by at least one processing device perform the following steps:

• maintaining a structural state of a multi-cloud application comprising a plurality of microservices hosted in at least two distinct cloud environments, wherein the at least two distinct cloud environments are provided by at least two different cloud providers and execute one or more of the microservices, wherein the structural state of the application is maintained over time and comprises, for each microservice, an indication of the cloud environment that hosts the respective microservice and an indication of one of a plurality of microservice technology types, wherein the plurality of microservice technology types comprises:
• a Container as a Service type and a Function as a Service type;
• obtaining a source code for each of the plurality of microservices of the multi-cloud application and deployment instructions for each of the distinct cloud environments;
• deploying the plurality of microservices of the multi-cloud application using the structural state of the multi-cloud application, the source code for each of the plurality of microservices and the deployment instructions for each of the distinct cloud environments;
• and
• migrating one of the plurality of microservices that is deployed on a first one of the at least two distinct cloud environments to a second one of the at least two distinct cloud environments, wherein at least another one of the plurality of microservices is maintained on the first one of the at least two distinct cloud environments, and wherein the at least one microservice is migrated from a first one of a plurality of microservice technology types to a second one of the plurality of microservice technology types.
