Cloud Infrastructure
Cloud infrastructure consists of all hardware and software components that are needed to support the delivery of cloud services to the customer. The main physical components of cloud infrastructure are networking equipment, servers and data storage. Cloud infrastructure also includes a hardware abstraction layer that enables the virtualization of resources and helps to drive down costs through economies of scale.
Public cloud service providers deliver cloud infrastructure and related services in three main delivery models: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS). The three delivery models vary in terms of which parts of the technology stack are outsourced and which aspects the customer will provide.
Key takeaways
- Instead of establishing their own on-premises IT infrastructure, a company can pay to rent cloud infrastructure and the related capabilities and components from a third-party cloud service provider.
- All three of the most widely adopted cloud architecture models — public, private, hybrid — use the same basic components of cloud infrastructure to deliver computing services.
- Each of the four components of cloud infrastructure plays a role in helping organizations successfully deploy and deliver applications and other services: network, servers, storage, virtualization.
- With Sumo Logic, organizations can take advantage of the cost-effectiveness of cloud infrastructure while maintaining the security of cloud-based applications and data assets.
