ISS Consulting offerscloud computing has three main types that are commonly referred to as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).Youcan rely on proven enterprise cloud security and hosting services.

Infrastructure-as-a-service (IaaS)

lets companies “rent” computing resources such as servers, networks, storage, and operating systems on a pay-per-use basis. IaaS providers host the infrastructure and handle tasks like system maintenance and backups – so customers don’t have to buy hardware or employ in-house experts to manage it.

Platform-as-a-service (PaaS)

provides acloud platform and tools to help developers build and deploy cloud applications. Users access PaaS from a Web browser, so there is no need to purchase and maintain the underlying hardware and software. With PaaS, developers can pick and choose the features they want on a subscription basis.

SaaS - software-as-a-service

is a way of delivering applications over the Internet. Customers can access SaaS applications right from a Web browser, which means there is no hardware or software to buy, install, maintain, or update. The SaaS provider takes care of everything – and the customer always has the latest version of the application.

What is cloud computing?

Simply put, cloud computing makes it possible for users to access data, applications, and services over the Internet. The cloud eliminates the need for costly hardware, such as hard drives and servers – and gives users the ability to work from anywhere. Over 90% of businesses are already using cloud technology in a public, private, or hybrid cloud environment. The major benefits of cloud include:

  • Elasticity: Scale up or down quickly to meet computing demand
  • Affordability: Only pay for what you use, and minimize hardware and IT costs
  • Availability: Get 24/7 cloud system access from anywhere, on any device
  • Simplicity: Free IT from managing servers and updating software

Cloud software offers a numberof distinct advantages that help sharpen your competitive edge.

The top 3 reasons to move to the cloud:

  • Use it to deploy faster, with lower upfront costs
  • Accelerate innovation cycles with hassle-free, more frequent updates
  • Leverage anytime scalability and dynamic capacity to boost flexibility and compete with big businesses

Public, private, or hybrid cloud?

Learn about the three types of cloud deployment models: public, private, and hybrid – and find out which one makes the most sense for your business.

Public Cloud

With a public cloud, services are delivered to customers over a network that’s open for public usage. Public clouds offer efficiency and affordability,and are often multi-tenant-meaning the provider runs your service in a shared environment.

Private Cloud

With a private cloud, services are maintained on a private network protected by a firewall. You can build a private cloud within your own data center or subscribe to one hosted by a vendor. Private clouds offer the most security and control.

Hybrid Cloud

A hybrid cloud is a composition of two or more clouds (public or private) – often from multiple providers. Hybrid clouds offer variety, so you can pick and choose which aspects of your business to include in a hybrid landscape, a build of both cloud and on-premise.
