Keeping Applications Connected in a Hybrid Cloud

What is a hybrid cloud? In an ideal hybrid cloud platform, you get the benefits of both private and public clouds. You can create, roll out and manage numerous types of applications. These applications should be able to span across different providers, clusters and data centers and be compatible with the management systems of different vendors and edge environments.

Technologies are usually seen as diffrent from each other, but they work together to enable application connectivity in a hybrid cloud. Properly managed, a hybrid cloud network deals with traffic and low and high-level connectivity. Services also need to be isolated and have rate limits to prevent maxing out resources.

Understanding Hybrid Cloud Connectivity for Applications

All applications need connectivity to function, regardless of whether they are front-end or back-end.

Key factors include how you make applications accessible to users and customers while keeping them secure, how you connect services to other services, and how you utilize third-party services without interfering with the normal application function.

Keeping Applications Connected

Different concerns for modern applications include the control plane, which is used to set up connectivity policies and the data plane, which balances traffic by controlling the flow of requests and responses. Data planes are typically placed on the cluster itself, while the control plane can be inside or outside the cluster.

Things to Keep in Mind When Developing a Hybrid Cloud Data Strategy

Keep flow and API interservice calls under control with traffic management, making the network more reliable when hit with heavy traffic and lots of requests.

Use service identity and security to protect traffic regardless of which network it's in and verify services' identity and validity. Enforce policies to ensure that resources are distributed evenly and equitably between users. Changes to the policy happen with the mesh configuration rather than the application code. With telemetry, you achieve a clear picture of how services interact and how traffic flows between the different services. This baseline makes it easier to spot potential problems.

Application Programming Interfaces

APIs are essential for the smooth operation of a business-based hybrid cloud. They support controlled access to services so that customers are directed to the right service to meet their needs. API serves such vital functions as rate limiting, which puts a maximum quota on the number of requests to the API. It also authenticates and authorizes users and accounts, ensuring that only authorized users and valid customers have access to services.


Cloud platforms and clusters continue to interact more and more closely, and applications operate over increasingly complex parameters and network connections. This is why hybrid cloud is important to so many industries. Keeping up with these changes is essential to maintain quality of service, keep data secure and prevent attacks.

Many facets are involved in managing applications and the cloud, including adapting legacy applications and developing new ones in ways that won't impact existing services. How services depend on each other is just as important as how they rely on the cloud.
