Computing as a service over the internet
1. Cloud computing, often referred to as simply “the cloud,” is the delivery of on-demand computing resources — everything from applications to data centers — over the internet on a pay-for-use basis.
2. Elastic resources — Scale up or down quickly and easily to meet demand
3. Metered service so you only pay for what you use
4. Self service — All the IT resources you need with self-service access
The cloud built for you. With you. By you.
The IBM Cloud has been built to help you solve problems and advance opportunities in a world flush with data. Whether it’s data you possess, data outside your firewall, or data that’s coming, the IBM Cloud helps you protect it, move it, integrate it and unlock intelligence from it — giving you what it takes to prevail in a competitive market.
Platform as a service (PaaS)
Platform as a service provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications — without the cost and complexity of buying and managing the underlying hardware, software, provisioning, and hosting.
The benefits of PaaS
1. Develop applications and get to market faster
2. Deploy new web applications to the cloud in minutes
3. Reduce complexity with middleware as a service
Software as a service (SaaS)
1. Cloud-based applications — or software as a service — run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the internet and, usually, a web browser.
The benefits of SaaS
2. You can sign up and rapidly start using innovative business apps
3. Apps and data are accessible from any connected computer
4. No data is lost if your computer breaks, as data is in the cloud The service is able to dynamically scale to usage needs
Infrastructure as a service (IaaS)
Infrastructure as a service provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.
The benefits of IaaS
1. No need to invest in your own hardware
2. Infrastructure scales on demand to support dynamic workloads
3. Flexible, innovative services available on demand
Public clouds are owned and operated by companies that offer rapid access over a public network to affordable computing resources. With public cloud services, users don’t need to purchase hardware, software, or supporting infrastructure, which is owned and managed by providers.
Key aspects of public cloud
1. Innovative SaaS business apps for applications ranging from customer resource management (CRM) to transaction management and data analytics
2. Flexible, scalable IaaS for storage and compute services on a moment’s notice
3. Powerful PaaS for cloud-based application development and deployment environments
IBM Cloud lets you choose the right compute model for your workload and quickly deploy over 120 services – including IBM Watson services.
