Is the cloud safe?
A topic debated by businesses and making many hesitant to take the plunge and transfer to the cloud is the fact that it leaves your data somewhat vulnerable to ‘the internet’. Although there are some concerns regarding the security of the cloud, some cloud managed services such as those offered by CiS have additionally built-in security for this very reason. With advances in technology allowing cloud service providers to predict the direction cybercrime will take, so can cloud providers take matters into their own hands and ensure their customers – ie. normal businesses- can rely on the cloud without their sensitive data falling victim to data breach or theft.
Types of cloud computing
The different models, types and cloud services available differ more than ever before, meaning businesses can find a cloud service that suits their exact needs, allows for growth and expansion, but doesn’t unnecessarily complicate things. We touch on the main types of cloud computing below:
Public cloud hosting
- Account is owned/operated by a third party cloud host provider
- Resources such as servers and storage are delivered over the internet
- Hardware, software and support information is all directly owned and managed by the cloud provider, done so over a web browser
Private cloud hosting
- With private cloud hosting, cloud computing resources are accessed specifically by one company, ie, working on a completely private network.
- A single company or business has the cloud network physically located on-site in a data centre, with some companies outsourcing to service providers for some infrastructure services.
Hybrid cloud hosting
- Hybrid cloud is the latest development in cloud computing technology and features a combination of both private and public cloud hosting.
- This advancement has largely been developed to give businesses increasing levels of flexibility. With various deployment options, access is available to those who need it, when they need it.
- Hybrid cloud hosting helps to optimise a company’s existing infrastructure, security and compliance to factor in 3rd parties as and when appropriate.
Types of cloud service
Infrastructure as a Service (IaaS)
The most basic form of cloud computing.
IT infrastructure includes:
- Virtual machines
Infrastructure as a service would be delivered by cloud service providers such as CIS on a pay as you go basis. IaaS uses public cloud managed services while still providing a full range of services including scalable databases, virtual private networks, big data analytics, developer tools, machine learning or application monitoring.
Many view IaaS as the fundamental building block for Cloud IT. IaaS offers, in many ways, the highest level of flexibility due to the fact that it is accessible by a web browser.
For those concerned about levels of security, here at CIS, we offer cloud service solutions with advanced security measures for complete peace of mind, as well as a dedicated team who are on hand to assist as and when appropriate or necessary.
Software as a Service (SaaS)
SaaS is a method of delivering software applications in a variety of forms, including:
- Over the internet
- On a subscription basis
When companies use SaaS, cloud managed services and cloud hosting providers host and manage software applications for their customers, and handle all the maintenance of software upgrades and security patching.
SaaS also offers options for addons and modifications, which can benefit companies working closely with customers. Configuration options on a case by case basis are one of the main features of SaaS, and SaaS is the type of cloud computing behind both Google Suite (email, calendar) and Office 365.
SaaS eliminates the need for organisations to install and run applications on their own computers and own data centres and is a popular cloud computing option.
Platform as a Service (PaaS)
This type of service provides separate sets of services and workflows that specifically target developers.
This way of working removes the need for companies to concern themselves with underlying infrastructure maintenance, and rather focus on the actual management of the software applications and deployment. The tools, processes and APIs are shared to allow for maximum development. PaaS, in general, helps with efficiency – capacity planning, software maintenance, developer tools, database management systems, you name it – these all fall under the umbrella of providing Platform as a Service.
