While cloud-native applications enable organizations to reap benefits such as portability and efficient use of resources. However, if they are not configured properly it can also damage the infrastructure.
The cloud-native application developers have grown at an exponential rate. In fact, as per a 2021 report from Developer Economics, titled “The State of Cloud Native Development,” the global cloud-native application developers have surged to 6.8 million. This rapid increase in the cloud-native application market has grown due to its range of benefits. These applications provide granular benefits, portability, and efficient use of resources. Yet, they are often too difficult to manage as well as challenging to secure.
Today’s cloud-native application developers should take steps towards minimizing their disadvantages while maximizing their benefits. They should comply with best practices when developing their cloud-native applications. These can range from choosing the appropriate design patterns to embedding security from the beginning of the application development to avoid issues later.
Here are a few approaches that IT organizations should incorporate while advancing their cloud-native application development:
Keep away from vendor lock-in
A cloud-native application should run in any IT environment and should not be dependent on any other platform. However, to reap the benefits of this portability of cloud-native applications, IT organizations should stop utilizing services that are tied to a specific vendor. Instead, they should ensure that cloud-native applications are not relying on a particular vendor service or feature in its environment to operate. At the same time, they should ensure that they do not utilize PaaS products that let their developers build and deploy applications to a specific cloud or host environment.
Opt for the right design pattern
Today’s developers have many preferences when designing a cloud-native application. While there are multiple design patterns for cloud-native applications, the most common ones consist of sidecar, event-driven, CQRS, and Gatekeeper.
Cloud-native developers can use many design patterns concurrently which are not mutually exclusive. When deciding to incorporate the design pattern, they should consider how these will reflect the use goals of the application and the priorities of the organization.
Embed security from the very beginning
The increased vulnerabilities of cloud products and services have revealed that not taking the right security measures can lead organizations to multiple cyber threats. Incorporating it only after building the application can prevent the cloud-native developers from addressing the vulnerabilities from the very beginning.
To effectively deal with it, organizations should define policies to ensure secure cloud-native application development. These should have guidance for planning, implementing secure application authentication, and practices for developers to prevent them from creating any business functionality as well as tackling authentication later on.
They should strive to maximize the security of application data. This includes data residing inside the application and data hosted externally. Organizations should ensure that they have data encryption and access control features across multiple storage locations.
Have the option of on-premise deployment
Cloud-native applications do not mean they can only operate on cloud; they can also function on the premise. At times on-premise deployments are a great choice since it delivers a lower total cost of ownership than hosting an application in the cloud environment itself. For specific use cases, on-premises may also provide better security and data privacy controls than is possible in the public cloud. Thus, when developing their application, cloud-native developers should design applications that can run seamlessly anywhere.
