TYPES OF CLOUD COMPUTING
Not all clouds are the same and not one type of cloud computing is right for everyone. Several different models, types and services have evolved to help offer the right solution for your needs.
First, you need to determine the type of cloud deployment, or cloud computing architecture, that your cloud services will be implemented on. There are three different ways to deploy cloud services: on a public cloud, private cloud or hybrid cloud.
PUBLIC CLOUD
Public clouds are owned and operated by third-party cloud service providers, who deliver their computing resources such as servers and storage over the Internet. Microsoft Azure, Amazon Web Services (AWS) and Google Cloud are examples of a public cloud. With a public cloud, all hardware, software and other supporting infrastructure are owned and managed by the cloud provider. You access these services and manage your account using a web browser.
Shared | Open | Pay-Per-Use
- An easily deployed virtual server on a shared hosting infrastructure.
- Quickly or automatically scale your servers according to workload.
- Per-Per-use for unlimited computing resource, storage and bandwidth.
What to Buy
- Guaranteed performance QoS.
Easy deployment and scaling. - SSD Storage for faster servers
- Quality cloud engineering
Pricing
- Variable Pay-Per-Use bandwidth and scaling mean price varies with traffic.
PRIVATE CLOUD
A private cloud refers to cloud computing resources used exclusively by a single business or organisation. A private cloud can be physically located on the company’s on-site data centre.
Some companies also pay third-party service providers to host their private cloud. A private cloud is one in which the services and infrastructure are maintained on a private network.
Dedicated | Secure | Fixed Cost
- A secure virtual data center on your own dedicated infrastructure.
- Servers and storage can be added and scaled according to your needs.
- Planned resource capacity with fixed costs and unmetered bandwidth.
What to Buy
- Fast, redundant network.
- Service reliability and support.
- Hardware choice and quality.
- Virtualization software choice.
Pricing
- Fixed unmetered bandwidth and fixed hardware means price doesn’t vary with traffic.
HYBRID CLOUD
Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them.
By allowing data and applications to move between private and public clouds, a hybrid cloud gives your business greater flexibility, more deployment options and helps optimise your existing infrastructure, security and compliance.
Pick from the best of both worlds
- A mix of dedicated infrastructure and public cloud infrastructure.
- Cherry-pick the best infrastructure for your different services.
- Keep data secure and control costs and resources with dedicated infrastructure.
What to Buy
- Custom solutions and service.
- Service reliability and support.
- Hardware choice and quality.
- Public cloud quality.
Pricing
- Fixed + Variable Certain services or traffic spikes are Pay-Per-Use while core services are fixed.
