Different types of cloud services

The many benefits of cloud computing have been discussed in depth and are rarely disputed.

With a lower cost, more flexibility, productivity and layers of security it is the obvious choice for most businesses.  However, there are several types of cloud services and knowing what is available can help you make better decisions on what you need.

The cloud computing stack

The national institute of standards and technology defines cloud computing as a model which enables useful, on-demand network access to a shared configurable resources (networks, storage, servers, services, and applications) which can be quickly implemented and released with minimum effort.  Here we look at the main elements of the cloud computing, often called ‘stack’ as they often build on top of each other to form solutions.

Software as a service (SaaS)

This is the term for software applications that are hosted in the cloud and make available to users over the internet. Usually they are on demand and come with a subscription cost.  Microsoft Office 365 is a perfect example but there are many others.  Cloud providers host and manage the software application which means that they look after upgrades and security issues.

When it comes to cloud we also need to evaluate the different options available be it public, private or hybrid.   Not all options are the same and making the correct decision for a business without advice can be difficult.

Platform as a service (PaaS)

This is a suite of services that are offered to make coding, developing, testing and deploying of applications easier in the cloud.  It is designed to make this process easier and quicker to create without having the concerns around managing infrastructures such as storage, databases or servers.

Infrastructure as a service (IaaS)

This is the one we may be more familiar with and the main foundations of the cloud.  It is the software and hardware used to create the cloud offering that an organisation will rent.  It will be the servers, storage, operating systems, virtual machines that the cloud provider puts in place so you can avail of cloud on a pay as you go basis.

Public cloud

Public cloud would be the most common option as it has all the benefits and is easily accessible by any business.  Microsoft Azure is an example of a public cloud.  They own and manage the computing resource and offer storage over the internet on a pay as you go basis.

Private cloud

Sometimes an organisation will require dedicated storage space, particularly when it comes to enterprise organisations.  IBM Bluemix offer such a service and will assign a particular area of the network exclusively for their use.

Hybrid cloud

Hybrid Cloud is a mix of cloud and onsite infrastructure.  For a variety of reasons this solution can be the best option when it comes to greater flexibility and deployment within the business.

Whatever options you decide are right for you ensure you are well informed.  A conversation with a cloud expert can reap rewards for the future and the team at DNA IT Solutions are available to take a look at your business and advise you accordingly.
