This article mainly shows you "what are the advantages of OpenStack", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "what are the advantages of OpenStack" this article?

1. Uniformly manage heterogeneous resource layers

OpenStack has a wide range of heterogeneous support capabilities, can provide a complete, simplified, TCO optimal hybrid architecture management platform, ensuring that on an integrated platform, through open API, traditional IT and

Various virtual environments, mainstream public clouds and private clouds are included in the management category, and resources can be flexibly scheduled according to workload attributes; openness enables enterprises to prevent being locked by a single vendor and technology, while taking into account security, performance and compliance issues, so that enterprises can more confidently apply cloud services to accelerate business innovation.

2. Strong unified process scheduling

With the rise of cloud, more and more enterprises are using OpenStack to build private cloud. However, the applications of different enterprises are very different. How to schedule all kinds of applications and loads on an OpenStack platform, its complexity and multi-dimensional management are usually exhausting. In OpenStack, Heat is a service that orchestrates composite cloud applications based on templates.

It currently supports Amazon's Cloud Formation template format as well as Heat's own Hot template format. The template supports a wide range of resource types, covering not only common infrastructure, including computing, network, storage, and mirroring, but also advanced resources such as Ceilometer alerts, Sahara clusters, Trove instances, etc. The use of templates greatly simplifies the definition and deployment of complex infrastructure, services, and applications.

After the emergence of container Docker technology, how to better integrate and arrange container resources has become a key technical function point of OpenStack. In the process of integration of OpenStack and Docker, a good integration point has not been found. Although attempts have been made to integrate with Nova and Heat, the shortcomings are obvious, so the community started a new project Magnum for Docker and OpenStack integration, which is used to provide container services.

The main purpose of Mangum is to provide Container services, and it can also be integrated with multiple Docker cluster management systems, including K8S, MESOS, Swarm, CoreOS and so on. Through the integration with these platforms, users can easily schedule their own and Docker cluster management resource system through OpenStack cloud platform, and promote the integration of Docker and OpenStack ecosystem.

3. Multi-cloud deployment and interoperability

Where is the future of OpenStack? Jonathan Bryce's answer at the Barcelona summit was straightforward: multi-cloud deployment and interoperability. Since the split pattern of cloud computing in the first half is not conducive to user practice, then open source must work on this user pain point, which is also the original intention and value of open source.

The diversity and foundation of OpenStack can integrate public and private clouds and enhance the application of innovative technologies such as containers, the Internet of things, and virtual reality. The 16 enterprises in the OpenStack ecosystem jointly demonstrated OpenStack's significant advances in application portability in diverse public and private clouds, enabling the same application and automated tools to run on all OpenStack-driven distributed and public clouds.

Interoperability is the focus of OpenStack, and collaboration is mentioned among the three issues mentioned by Deutsche Telegraph at this summit. It is worth mentioning that domestic Huawei, EasyStack, UntiedStack and other enterprises have also passed the OpenStack interoperability certification.

4. DevOps across multi-cloud platforms

In order to deliver applications and services faster, more secure, and with a lower budget, constantly experimenting with new technologies and services has become an explicit requirement of enterprise IT departments. OpenStack supports DevOps processes for both traditional and native cloud applications, allowing developers to rapidly develop, deploy and scale native cloud applications and support a broad and growing list of programming languages and technologies. In view of the complexity of cloud management, the workflow channel of continuous integration / continuous delivery (CI/CD) enables development and operations teams to get rid of isolation and collaborate seamlessly.

This is a cloudy era, whether enterprises can adapt to IT changes faster and better depends to a large extent on cloud management. Simple and efficient hybrid cloud management has become the common requirement of enterprise IT in multi-cloud environment. It is also a wise choice for us to use OpenStack to help us manage the hybrid cloud to meet the needs of each business unit and maximize value.
