Introduction to OpenStackOpenStack is a set of open-source software modules and tools that serve as a foundation for building and managing public and private cloud infrastructure. OpenStack allows users to create VMs (virtual machines) and other instances for a cloud environment with ease. It helps to provision, pool, and manage enormous clusters for computing, storage, and network resources for infrastructure-as-a-service platforms. OpenStack dashboard and APIs (Application Programming Interfaces) help manage bare metal hardware, VMs, and containers. The vast developer community is working and improving OpenStack every day, making it more robust and highly secure. Other OpenStack components enable high-availability operations by providing orchestration, fault management, and services. As per a report by Statista, the OpenStack market size has grown from 0.85 billion USD in 2014 to 6.73 billion USD in 2021.
Top 5 Advantages of opting for OpenStackThe public cloud market is a competitive space, with many players trying to capture the growing market share. OpenStack has impacted this area as well and offers benefits for your business. The key to its success is providing a solution that allows customers, developers, and cloud providers greater control over their infrastructure than other platforms. It offers robust features and supports large-scale deployments, high availability, data protection, scalability, flexibility, and reliability. Here are the top 5 reasons to opt for OpenStack for your business:
- Top-notch industry support – OpenStack was founded as a framework for allowing enterprises to deliver free and open-source cloud computing services using even basic hardware. Since its establishment, many IT behemoths have supported it and invested in its growth, giving rise to a robust developer community that collaborates with users to provide the ideal platform for each business requirement.
- Compatible – OpenStack APIs work with public cloud systems, making them compatible and allowing easy porting of IaaS (Infrastructure as a Service) client applications from proprietary public cloud platforms to OpenStack-based IaaS providers.
- Scalable – OpenStack public clouds are highly scalable as they allow enterprises to obtain more servers than just deploying larger servers. It is designed to control large pools of computing, storage, and networking resources throughout a data center, giving businesses the ability to spin servers up and down quickly.
- Highly secure – Securing an OpenStack cloud is like securing any other IT infrastructure. It necessitates a diverse collection of tools and abilities and a thorough grasp of security with the help of role-based access restrictions with varying levels of access.
- Convenient control panel – OpenStack has an easily accessible control panel that gives visibility, control, and quick access to power management capabilities. As a result, customers find it extremely simple to monitor and control their cloud services by gaining a clear picture of resource utilization.
How does OpenStack play a crucial role in Public Cloud?According to Statista, OpenStack is the most widely used open-source platform for constructing public cloud environments. The fact that you can use OpenStack to deploy your cloud regardless of the size of your company or business is something worth emphasizing. It offers a robust basis for your cloud solutions, from containers to virtual machines, being both practical and economical, irrespective of your industry. OpenStack is more than just virtualization technology and provides orchestration capabilities to help you manage your infrastructure more efficiently. It utilizes your current virtualized infrastructure, built using a well-known hypervisor (such as KVM, VMware vSphere, or Microsoft Hyper-V) to construct a cloud computing environment such as a public or private cloud. It allows broad provisioning, lifecycle automation, orchestration, user self-service, cost reporting and billing, and other functions.
What are the use cases of OpenStack?OpenStack is drastically changing the rules of IT infrastructure, providing users with a path toward software-defined virtual data centers. Enterprise clients and service providers use OpenStack to transform their business models by reshaping their IT use cases. Here are a few examples of how enterprises are leveraging the agility and scalability of OpenStack:
- Public cloud – OpenStack is one of the most popular open-source platforms for deploying public cloud infrastructure. Whether your organization is a multibillion-dollar publicly listed corporation or a startup, you may use it to set up public clouds with services that compete with large public cloud providers.
- Creating containers – Container portability requires developers and operations to effectively develop, test and deploy applications across public and private environments. OpenStack provides an accessible platform for large-scale container orchestration, and it also allows a single, wizard-driven means of provisioning new clusters and scaling existing ones. Moreover, containerized applications are deployed on OpenStack with full automation, including virtual machines and networks.
- Network functions virtualization – As OpenStack is an open-source platform for virtualization, it enables service providers and corporations to deploy network functions on commodity server hardware and handle their workloads. These applications also rely on OpenStack for their hosting in the cloud.
- Private Cloud – OpenStack’s private cloud distributions can provide more significant benefits than custom-coded private clouds. Hosted private cloud (where businesses pay a cloud service provider for support and maintenance) or on-premise private clouds are more secure but come with the cost of more maintenance and higher expenses for running them as organizations need to hire employees for running the servers.
How does OpenStack work?OpenStack leverages two more fundamental technologies: a base operating system like Linux and a virtualization platform like VMware or Citrix. The virtualization engine oversees the visualized hardware resources required by OpenStack projects, while the OS handles the instructions and data transferred from OpenStack. Administrators may supply and manage the instanced resources that applications require once the OS, virtualization platform, and OpenStack components have been correctly deployed and configured. The dashboard’s actions and requests result in a sequence of API calls authenticated by the security service and forwarded to the destination component, which performs the corresponding duties. An administrator, for example, logs into OpenStack and oversees the cloud environment via a dashboard. They may build, connect, and define network behavior for new computing and storage instances and can also use the API to connect to other services, such as monitoring the performance of a provided sample and using resource billing and charge-back.
Major Components of OpenStackMost OpenStack users start with a modest set of core components and gradually add more to expand their cloud’s operational and business capabilities over time. OpenStack comprises several components with different code names and a modular design. Let us take a quick look at the OpenStack components: Let us know about each of them in detail:
- Dashboard (Horizon) – OpenStack Horizon is the official graphical interface for automating cloud-based resources and is the only component visible to users as a Dashboard. It provides third-party services such as monitoring, billing, and other management tools to service providers and commercial vendors.
- Identity Service (Keystone) – OpenStack Keystone keeps a master list of all OpenStack cloud users, matched to all cloud services for which they have permission. It connects with current back-end services like LDAP while serving as a centralized authentication mechanism for the cloud computing infrastructure. The catalog also includes an endpoint registry of a searchable list of services installed in an OpenStack-based cloud.
- Object Storage (Swift) – OpenStack Swift builds redundant and scalable data storage. The stored data can then be used, retrieved, and modified. It features a distributed design that improves redundancy, scalability, and performance. Swift is object storage that is widely available, shareable, and finally consistent and hence enables businesses to store substantial amounts of data in a secure, cost-effective, and efficient manner. Swift guarantees data replication and distribution across several devices, making it perfect for scale-out storage at a low cost.
- Image Service (Glance) – OpenStack Glance assists in discovering, registering, and restoring virtual machine images. It has a client-server architecture and provides a REST API allowing users to query virtual machine image information and receive the actual image. Glance uses the cached pictures as templates for deploying new VM instances.
