With enterprises depending heavily on the Internet to run their businesses, cloud infrastructure has become an attractive proposition from an entrepreneur’s viewpoint. Thankfully, cloud infrastructure management tools come in various open-source avatars.
What is Cloud Computing?
Cloud computing refers to the delivery of various computing services—such as servers, storage, databases, networking, software, and more—over the Internet (“the cloud”). This technology allows users to access these resources from a variety of devices, including PCs, laptops, smartphones, and tablets. It offers a range of benefits, from reduced costs and increased efficiency to greater flexibility and performance.
In 2011, the National Institute of Standards and Technology (NIST) defined cloud computing as “…a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources.” Essentially, cloud computing provides five key characteristics:
- On-demand self-service
- Broad network access
- Resource pooling
- Rapid elasticity
- Measured service
These characteristics can be aligned with three service delivery models:
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Infrastructure as a Service (IaaS)
Additionally, cloud computing encompasses three deployment models:
- Private Cloud
- Public Cloud
- Hybrid Cloud
Cost-Efficiency and Resource Management
Cloud computing is notably cost-effective. By reducing the need for substantial IT teams and expensive infrastructure, organizations can channel their resources toward core operations. Data is stored closer to where it is utilized, enhancing reliability and security. The shift to cloud services enables operations like data analytics, scientific calculations, and gaming to run more efficiently.
Cloud Infrastructure Management
The escalating importance of cloud computing, especially with the integration of emerging technologies like machine learning and Big Data, has made effective cloud infrastructure management a top priority. Microsoft reported that the global hybrid cloud market grew 78% year over year in 2017, signaling a robust demand for effective cloud services.
Cloud infrastructure management encapsulates the on-demand services provided through IaaS models, granting enterprises access to shared pools of configurable resources. This allows organizations to focus on their own goals while ensuring optimal management, automation, and governance from a single console.
Open Source Cloud Infrastructure Management Tools
OpenStack
Founded in 2010 through a collaboration between Rackspace and NASA, OpenStack has evolved into a powerhouse of open-source tools that create and manage public and private clouds. This extensive software supports a vast array of compute, storage, and networking resources, all managed through an intuitive dashboard.
OpenStack primarily consists of:
- Keystone: Handles authentication and authorization.
- Nova: Manages compute resources.
- Neutron: Responsible for networking.
- Glance: Manages server images.
- Cinder: Offers block storage.
- Swift: Facilitates object storage.
