OpenStack is not always the perfect choice, but it does offer unique capabilities that are attractive to many organisations.<\/p>\n<p>Consider sectors such as <strong>healthcare<\/strong>, where data compliance is crucial, or at financial institutions that have high security requirements.<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"731\" src=\"https:\/\/www.combell.com\/en\/blog\/files\/openstack-controlpanel-1024x731.png\" alt=\"OpenStack is a set of software tools for managing cloud computing platforms.\" class=\"wp-image-12960\" srcset=\"https:\/\/www.combell.com\/en\/blog\/files\/openstack-controlpanel-1024x731.png 1024w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-controlpanel-300x214.png 300w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-controlpanel-768x549.png 768w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-controlpanel.png 1400w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">OpenStack is a set of software tools for managing cloud computing platforms.<\/figcaption><\/figure>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Why do we need OpenStack?<\/h3>\n<p>With OpenStack, you can remain independent of large cloud providers such as AWS, Google Cloud or Azure. This is especially important for companies that want to maintain control over their data and infrastructure.<\/p>\n<p>For example, in a <a href=\"https:\/\/www.combell.com\/en\/blog\/what-is-hybrid-cloud\/\" rel=\"noreferrer noopener\" target=\"_blank\">hybrid cloud setup<\/a>, an organisation can store sensitive data locally while less critical applications are outsourced to a public cloud.<\/p>\n<p>In addition, <strong>OpenStack helps save costs,<\/strong> especially for organisations with a long-term cloud strategy.<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h4 class=\"wp-block-heading\">OpenStack offers customization<\/h4>\n<p>Another big advantage is the possibility of customisation. Companies can customise OpenStack to support specific operational needs.<\/p>\n<p>Imagine a large webshop that needs to handle peak loads during holidays; OpenStack allows <em>on-demand <\/em>capacity to be increased and then scaled back. This gives organisations the <strong>flexibility <\/strong>they need to stay competitive.<\/p>\n<p>For businesses that need a unique cloud strategy, OpenStack is a logical choice. The<\/p>\n<p>Open Source model of the platform means businesses have no <em><a href=\"https:\/\/en.wikipedia.org\/wiki\/Vendor_lock-in\" rel=\"noreferrer noopener\" target=\"_blank\">vendor lock-in<\/a><\/em>, increasing their technology independence.<\/p>\n<p>OpenStack has up to a wide range of integration capabilities with other technologies, enhancing interoperability.<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"731\" src=\"https:\/\/www.combell.com\/en\/blog\/files\/openstack-blueprint-1024x731.png\" alt=\"OpenStack is suitable for building private and public clouds.\" class=\"wp-image-12961\" srcset=\"https:\/\/www.combell.com\/en\/blog\/files\/openstack-blueprint-1024x731.png 1024w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-blueprint-300x214.png 300w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-blueprint-768x549.png 768w, https:\/\/www.combell.com\/en\/blog\/files\/openstack-blueprint.png 1400w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">OpenStack is suitable for building private and public clouds.<\/figcaption><\/figure>\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h2 class=\"wp-block-heading\">How does OpenStack work?<\/h2>\n<p>OpenStack functions as an abstraction layer over physical hardware (such as servers). It uses <strong>virtualization<\/strong> to manage servers, storage, and networks.<\/p>\n<p>Thanks to APIs (<strong>Application Programming Interfaces<\/strong>), users can easily request and manage resources without interacting directly with the hardware. This enables organizations to <strong>manage and optimize their infrastructure efficiently.<\/strong><\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Collaboration with other technologies<\/h3>\n<p>OpenStack is designed to work seamlessly with popular technologies like Kubernetes, Docker, and Ceph.<\/p>\n<p>This integration allows businesses to incorporate OpenStack into existing workflows and benefit from the best of both worlds. This interoperability makes OpenStack a versatile choice for modern IT environments.<\/p>\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">The purpose of OpenStack projects<\/h3>\n<p>OpenStack consists of a collection of projects, each with a specific goal.
