Cloud-Native- A Solution for Organizations



Cloud-Native- A Solution for Organizations

Introduction: Cloud Native

It is in recent times that the term cloud-native has come to use largely. And before we go deep into this, let us understand what is it and what are its attributions?

Cloud-native is a way with which the developers build and run applications by taking full advantage of the benefits of the cloud computing delivery model and container orchestration. Cloud-native applications are developed to run in the cloud, taking away the attention from machines to the actual services.

As the microservices are used during the architecture of the cloud-native applications in place of monolithic application structure, they depend on the containers for the packaging of the application’s libraries and processes for placement. These microservices permit the developers to make peaceable apps that are made as individual modules focused on executing single service.

The container orchestration tools help the makers of the applications to synchronize how an application’s containers will function, along with the scaling and deployment.

While talking about the development of the cloud-native app, it needs a shift to a DevOps operating structure. And this shift leads to the working of development and operations teams together, for a faster and smoother production process.

Now below are some of the attributes of cloud-native applications-

  1. Cloud-native applications are packaged as lightweight containers.
  2. These are built with best-of-breed languages and frameworks.
  3. These are structured as loosely coupled microservices.
  4. The cloud-native apps are centered on APIs for interaction and collaboration.
  5. These are deployed on self-service, elastic, and cloud infrastructure.

By now we know what cloud-native is and what its attributes are. So, now we will move on to the principles of cloud-native architecture -

Principle-1: Build for automation

While you are working on the development of the software systems, automation has always turned out to be the best option. And the cloud has made it easier to automate the architecture along with the components that are to be placed above it. As the upfront investment is most of the times higher, preferring an automated solution over it will every time pay off for the efforts of the system. It also turns out to be the best in terms of resilience and performance of the system. The automated processes help in repairing, scaling, and deploying your system quicker than the people can do it.

One can automate the below-mentioned areas in cloud-native systems:

  1. Infrastructure
  2. Continuous Integration or Continuous Delivery
  3. Scale-up and scale-down of the system
  4. Monitoring and Recovery

Principle-2: Be careful with state

Be it the user data or the system state, the storing of the state is the toughest part of the cloud- native architecture. So, while you are developing your system, you should try to make it intentional about when and how to store state, and design components to be stateless wherever needed.

Stateless components are easy to:

  1. Scale: To scale up, all you need to do is to add more copies. While to scale down, train instances to dismiss once they are done with their current work.
  2. Repair: When you want to repair a failed instance of a component, just dismiss it as smoothly as possible and call for a replacement.
  3. Roll-back: In case you come across a bad deployment, stateless components can easily be rolled back, as you can dismiss them and plan to launch instances of the old version.
  4. Load-Balance across: If the components are stateless in the system, load balancing is much easier as any instance can manage any request. Load balancing in stateful components is tough.

Principle-3: Go for managed services

Most of the providers of the cloud, offer the users a perfect set of managed services, providing every kind of function which helps them to get rid of the pain to handle the backend software or architecture. Still, most of the companies prefer to be careful while taking advantage of these services because they are worried about being locked into a given provider. Though the concern is valid on its part, managed services can frequently save the firms immensely in time and operational overhead.

Principle-4: Practice defense

Traditional architectures trust perimeter security a lot and mainly a hardened network perimeter with all the reliable things inside and untrusted things outside. But sadly, this method has always turned out to be vulnerable to insider attacks and external threats. Besides this, the growing pressure to provide flexible and mobile working has furthermore undermined the network perimeter.

Cloud-native architectures, very frequently come across external attacks and so, they prefer to go with an approach of defense-in-depth by applying authentication between each component, and by reducing the trust between those components. As a result, there is no inside and outside is left. The architectures can also add rate limiting and script injection for defense.

Principle-5: Keep architecting

One prominent characteristic of a cloud-native system is that it keeps evolving, and that is similarly true of the architecture. As a cloud-native architect, you should constantly try to refine, simplify and improve the architecture of the system with the continuous changes in the demands of the organization, the changes in the landscape of your IT systems, and the changes in the abilities of your cloud provider itself. The dead, ossifying IT systems will eventually bring the organization to a standstill situation making them unable to deal with the new threats and opportunities.

As we have talked about the principles of the cloud-native architecture let us just talk about its effect on our ecosystem. In the last few years, the technology around us has changed drastically. And, in the last 5 years, the technology of cloud-native computing has also evolved a lot. With the development of this, the way with which the software is developed has also changed. It has mainly affected the speed of the team’s working which has turned out to be beneficial for organizations in terms of dealing with the customers.

The cloud-native allows the companies to be competitive in big markets. It has become the reason for the success of many tech powerhouses and digital-native companies like cab services provider.

While well-developed cloud natives are best suited for the big organizations, the small enterprises work on creating the replicable of cloud-native frameworks to make profits from it.

Conclusion

If you are having a problem with adding new code to your software and facing issues in meeting the deadlines then cloud-native is a solution for you. It is the best option when it comes to timely deliveries and adding the new codes in the system.

It has been developed to help you to focus on customer-centricity, quality, and end-to-end visibility. It helps the organizations in assessment, selection of the correct methodology, platforms, services, and new-generation architectural patterns.

Though it might cost you a bit, it is highly beneficial for your business to grow and help teams to work efficiently and quickly. Here are a few Pros and cons of cloud-native architecture you should know well -

Pros:

  1. It makes the process of compliance quicker that is important for organizations.
  2. It takes care of all the bugs and slow loading speed.
  3. To assist a variant and growing customer base, cloud-native architecture has been allowing scalable developments. Also, Ii helps in managing variable costs.
  4. It is one of the most reliable technologies invented for organizations.
  5. According to its services, it is very cost-efficient.

Cons:

Though there are various advantages of cloud-native, there are a few drawbacks of the cloud- native:

  1. The cost you are paying for cloud-native might be high for some of the organizations.
  2. Applications that are stored on a specific cloud platform are not easy to transfer to other cloud platforms. It takes a lot of rewriting and refactoring of the code.
  3. If the applications will continue to run on the target cloud platform for a long time, the users will be limited to get back their investment in code changes and testing.
