Many of the clients we have served in the past, large and small, have been asked one question in their early technical communications: should we choose private cloud or public cloud?

This is an important choice, and if judged incorrectly, it can often put the organization or team at a disadvantage when it comes to the business and its goals of application development, data processing, or providing a good user experience.

But it is not a difficult choice. The deployment, scalability, ease of use, and flexibility of a private cloud are basically the same as those of a public cloud, except that they are more stringent in terms of control, performance, security, and management options. As long as we consider a few points clearly, we can get a clear answer —

1. Integration ability

In fact, most organizations of a certain size now choose hybrid clouds, deploying highly sensitive applications and services on private clouds and less sensitive applications and services on public clouds to achieve a balance between agile efficiency and cost. At the same time, there is an increasing tendency for the public cloud portion of enterprise hybrid cloud solutions to use multiple public cloud providers simultaneously.

In this case, the integration capability of the PaaS platform is critical. It should be able to move data or applications between private and public clouds, and between different public clouds.

2. Security

On the one hand, we need to consider the privacy of the data. If the data is very sensitive, it is obviously the most comfortable way to put it behind the firewall of the private cloud. If the data is not sensitive, it can be very economical to put it in the public cloud, and frankly the public cloud is getting better and better in terms of security.

On the other hand, data availability must be considered. Flexible capacity expansion, single-node/multi-contact high availability, multi-DATA center (MDC) and service-level monitoring are essential features of current PaaS.

3. Development support

In a “multi-cloud” world, where enterprises may need to deliver applications and services to a variety of environments, the shift to cloud-native applications will make IT easier for enterprise IT.

The support and application of microservices architecture, Docker, Kubernetes and DevOps workflows will also make development easier and more efficient.

4. Agility

Many traditional enterprises have a large number of legacy systems that were not originally designed for the cloud, but are relatively old but business-critical.

Our advice is not to abandon these investments, but to modernize them, use PaaS to unify the management infrastructure and SaaS legacy software, embrace cloud computing without waste, and enjoy the agility that cloud computing brings.
