OpenStack and OpenShift are popular open-source platforms for building and managing cloud infrastructure and containerized applications, respectively. OpenStack is a cloud infrastructure platform that provides a wide range of infrastructure services, such as computing, storage, and networking. It is designed to be scalable, flexible, and cost-effective, and developers can customise and extend it. However, it can be complex to deploy and manage, particularly at scale, and it requires significant expertise and resources to set up and maintain a production-ready OpenStack environment.

OpenShift, on the other hand, is a container application platform built on top of Kubernetes. It is designed for building, deploying, and managing containerized applications and strongly focuses on DevOps workflows. OpenShift is flexible and supports various programming languages, frameworks, and deployment options. However, it has a learning curve, particularly for organizations new to containerization and Kubernetes, and it requires a significant amount of computing and storage resources to operate effectively.

What is OpenStack?

OpenStack is an open-source cloud computing platform that provides software tools for building and managing cloud infrastructure. It was created in 2010 as a joint project between Rackspace Hosting and NASA to enable organizations to build and manage public or private cloud environments. OpenStack is designed to be highly scalable and flexible, allowing organizations to build customized cloud infrastructures that meet their specific needs. It consists of several core components, including:

Compute (Nova): provides virtual servers on demand, allowing users to launch and manage virtual machines.
Networking (Neutron): provides network connectivity as a service, enabling users to create and manage virtual networks.
Storage (Cinder and Swift): provides block and object storage services, respectively.
Identity (Keystone): provides authentication and authorization services for all OpenStack components.
Dashboard (Horizon): provides a web-based interface for managing and monitoring OpenStack resources.

Other components and services, such as telemetry, orchestration, and database services, can also be added to an OpenStack environment. OpenStack is used by many organizations, including enterprises, service providers, and government agencies, to build private, public, and hybrid cloud infrastructures. Its open-source nature makes it highly customizable and flexible, and it has a large and active community of contributors and users who continually improve and enhance the platform.

OpenStack Background

OpenStack was created in 2010 as a joint project between Rackspace Hosting and NASA. The two organizations joined forces to create an open-source cloud computing platform that could provide a more scalable and flexible alternative to proprietary cloud platforms. NASA was interested in using OpenStack for its Nebula cloud project, while Rackspace saw an opportunity to offer its customers a more customizable and cost-effective cloud platform.

Since its creation, OpenStack has become a global project with a large and diverse community of contributors and users. The project is managed by the OpenStack Foundation, a non-profit organization that oversees the development and promotion of the platform. The foundation is supported by many leading technology companies, including Red Hat, IBM, Intel, Huawei, and others, who contribute resources and expertise to help develop and improve the platform.

What is OpenShift?

OpenShift is a container application platform that enables developers to build, deploy, and manage applications on the cloud. It is based on the Kubernetes container orchestration system and is designed to simplify deploying and scaling containerized applications. OpenShift provides a platform-as-a-service (PaaS) layer that removes many of the complexities of managing containers and infrastructure, allowing developers to focus on writing and deploying their applications. It supports various programming languages and frameworks, including Java, Python, Node.js, and Ruby.

OpenShift includes several key features that make it a popular choice for developers and organizations, including:

Container orchestration: OpenShift uses Kubernetes to manage containerized applications and services, providing automated scaling, self-healing, and load balancing.
Developer tools: OpenShift provides a rich set of tools and integrations for developers, including integrated development environments (IDEs), source code management, continuous integration and delivery (CI/CD) pipelines, and more.
Hybrid cloud support: OpenShift can be run on public or private clouds and on-premises data centres, providing a flexible and scalable platform for deploying and managing applications.
Security and compliance: OpenShift includes built-in security features, such as role-based access control (RBAC), encryption, and secure networking, as well as compliance certifications for HIPAA, PCI, and other standards.

OpenShift is used by many organizations, from startups to large enterprises, to build and deploy containerized applications in a cloud-native way. Its open-source nature, rich feature set, and integrations make it popular for developers and DevOps teams who want a flexible and powerful application platform.

OpenShift Background

OpenShift was originally created by a company called Red Hat, now an IBM subsidiary. The platform was first released in 2011 as OpenShift Origin, an open-source PaaS platform that enabled developers to deploy and manage applications in the cloud. Since then, OpenShift has become a container application platform that supports various programming languages, frameworks, and deployment options. Red Hat has continued to invest in the platform, adding new features and capabilities to make it easier for developers to build, deploy, and manage containerized applications.

Today, OpenShift is used by many organizations, from startups to large enterprises, to build and deploy cloud-native applications. Red Hat and IBM continue to support and contribute to the development of OpenShift, while offering commercial versions of the platform with additional features and support services. OpenStack and OpenShift are different platforms for building and managing cloud infrastructure and applications. While both are open-source and developed by Red Hat, they have different architectures and use cases.

OpenStack vs OpenShift

OpenStack primarily provides infrastructure-as-a-service (IaaS) capabilities, such as virtual machines, storage, and networking. It is designed to be highly scalable and flexible, allowing organizations to build and manage public or private cloud environments. OpenShift, on the other hand, is a container application platform that enables developers to build, deploy, and manage containerized applications on the cloud. It is based on the Kubernetes container orchestration system and provides a platform-as-a-service (PaaS) layer that simplifies deploying and scaling containerized applications.

Here are some key differences between OpenStack and OpenShift:

Focus: OpenStack is focused on providing IaaS capabilities, while OpenShift is focused on providing a platform for building and deploying containerized applications.
Architecture: OpenStack is designed to be a set of loosely coupled components, while OpenShift is a more integrated platform with a strong focus on automation and DevOps workflows.
Containerization: OpenStack provides some support for containerization through projects like Magnum, but it is not a native container platform. OpenShift, on the other hand, is specifically designed for building and managing containerized applications.
Complexity: OpenStack can be complex to deploy and manage, particularly at scale. OpenShift is designed to simplify deploying and scaling containerized applications, making it easier for developers to focus on their code.
