What is OpenStack?
OpenStack is a collection of open source software tools for creating and managing public, private or hybrid cloud. OpenStack clouds are built by integrating various software projects. Core projects usually included in OpenStack clouds are:
A virtual machine deployed with OpenStack can be implemented for a multitude of use cases. This includes software-as-a-service delivery, container deployments, heterogeneous compute, and web hosting. OpenStack is currently used by organizations such as Nike, Verizon, Bloomberg, T-Mobile, Walmart, Target, Volkswagen, Rakuten, Progressive, Overstock.com, and many more. Learn more about who is using OpenStack.
How Does OpenStack Work?
OpenStack is a platform composed of several independent components. These components interoperate with each other through Application Programming Interface (API). These components are complementary, but do not depend on all other components to function properly. This grants you the ability to build your cloud with only the components you need.
This feature is what attracts so many users to OpenStack. You can build your cloud with the projects you need for your workload and not waste hardware resources on additional components which are not necessary for the functionality you require in your cloud. This is something you cannot get with public clouds that do not give you access to configuration at the root level.
What Are The Core OpenStack Projects?
CINDER: provides block storage service, it is responsible for virtualizing block storage devices and provides storage volumes for your compute resources. This OpenStack project allows you to access resources without knowing where the storage is actually deployed or on what type of device it’s on. Cinder achieves this by using either reverence implementation or plugin drivers for other storage devices.
Cinder Block storage is similar to AWS EBS.
If you want to use Cinder, you will also need Keystone.
Keystone: is used for client authentication, authorization, and service discovery. Keystone supports various authentication protocols such as LDAP, OAuth, OpenID Connect, SAML, and SQL for authentication and authorization. It is used as the identity service in OpenStack. Many applications depend on Keystone, so if you’re building an OpenStack cloud, it’s likely you will need this project.
Keystone is similar to AWS IAM (Identity and Access Management).
GLANCE: provides the image management service in your cloud. It grants you the ability to discover, register, and retrieve virtual machines, Docker, and bare metal images.
Glance is similar to AWS Amazon Machine Images.
NEUTRON: is responsible for delivering networking-as-a-service in the cloud. It is an SDN networking project. Neutron is used to provision virtual networks, subnets, ports, routers, and a variety of advanced networking services.
Neutron is similar to AWS Networking.
If you want to use Neutron, you will also need Keystone.
NOVA: provides you with quick access to compute resources, including bare metal, virtual machines, and containers. Nova also allows you to provision and manage your virtual machines (instances). Most OpenStack clouds include the Nova project because it grants you access to massively scalable on-demand compute resources. Nova uses the services of the networking project Neutron to provision a network port for your instance. What makes Nova extra special is that it was one of the first two OpenStack projects to be developed and released. Nova was NASA’s contribution to the founding of OpenStack.
A Nova Instance is similar to AWS EC2.
If you would like to use Nova, you will also need: Glance, Keystone, Neutron and Placement.
Swift: is an object storage service that is highly available, distributed, and scalable. Swift is the project you would turn to if you want to store unconstructed data that can grow indefinitely because it allows you to store data efficiently, safely, and cheaply. This project was developed by RackSpace and is one of the two projects that OpenStack was launched with. Swift is similar to AWS S3. Learn more about AWS S3 alternatives.
What Are The Pros Of Using OpenStack?
When you consider the list of major industry players using OpenStack, it is not surprising that there are many pros to using OpenStack. These include:
- Easy Scalability: With OpenStack, you can scale your cloud up or down at a bare metal level. This is beneficial if you are in an industry that has peaks or downtimes. You will have access to additional resources when you need them and you only pay for them when you use them. This allows you to keep up with your customers’ demands without exceeding your budget.
- Affordable: Because OpenStack is open source, the source code is available freely for public use. It was released as open source under the Apache 2.0 license. However, you will still have hardware costs unless you use an OpenStack vendor.
- Easy Automation: OpenStack has tools that can make cloud management easier. OpenStack also has its own API which allows other programs to tap into it. Developers can create their own solutions to automate tasks and share them with the OpenStack community. With more than a decade of contributions from the open source community, there are various automation tools available.
- Reliable: The OpenStack software has been improved on for over a decade. It gives you a tried and true approach. Any use you can think of for OpenStack has probably been thought of, tried, and tested.
- Fast Development: If a new OpenStack feature is being developed, it can be quickly worked on by a team of expert developers from around the world. This allows OpenStack to keep up with the fast-paced tech world.
- Vendor-neutral: With OpenStack, you will never have to deal with vendor lock-in because it is open source! If you do opt to use an OpenStack provider, it is easy to switch between vendors.
Now, you may have a clear understanding of why so many organizations turn to OpenStack. But before jumping headfirst into OpenStack, let’s consider some of the cons.
Why Would Organizations Seek OpenStack Alternatives?
- Manual Installation: OpenStack is a suite of projects and each of those applications needs to be configured to your needs. You will need an OpenStack expert or team of experts depending on the size of your project. Additionally, you will need expensive hardware and your engineers’ time will be allocated to setting up your cloud for weeks. This is usually the deal breaker for many small to medium sized businesses that need all hands on deck. But notice I specified manual installation; there are ways to get OpenStack installed without doing it yourself that I will address later on in this post.
- Consistency: As the open source community continues to contribute, the OpenStack component suite is always in flux as new components are added and others are deprecated.
- Support: OpenStack is not owned or directed by any one vendor or team. So, no one is responsible for providing support on your uniquely configured cloud.
