10 questions about cloud computing

We get asked plenty of questions about cloud computing, so here are the top 10 most frequently asked burning questions about the cloud, along with our answers…

1. How does active-active cloud work?
Unlike a single-site cloud solution, active-active architecture is essentially two cloud platforms linked together, running simultaneously. This means that any data or online assets that are saved to, modified, or updated on the primary platform, are automatically replicated to a secondary platform. These two platforms, which are geographically separate for resilience, then run identically to provide synchronised hosting environments, and your data can be served from either of these platforms at any given time.

2. What are the benefits of active-active cloud?
Active-active cloud brings increased levels of resilience compared to a single-site cloud solution. Building these levels of failover into your infrastructure yourself, can be costly and resource intensive. With CloudActiv, from Teledata, this is already done for you and built in, as standard.

3. What’s the difference between public cloud and private cloud?
Private cloud gives organisations a dedicated cloud environment, on hardware specifically built for that organisation’s requirements - with no shared resources. Essentially, an organisation has the cloud to themselves, which can bring the additional levels of security and data privacy which are required by some governing bodies. With public cloud, compute services and infrastructures are shared between a number of organisations. Each customer’s data and applications remain hidden and segregated from other customers.  Overall network resource is shared, but again customer data is completely segregated for security.

4. What are the benefits of cloud computing?
Cloud computing is scalable, resilient, secure, and cost effective, with extremely high levels of availability. It gives businesses access to enterprise grade levels of computing, at a fraction of the cost of building and maintaining their own systems.

5. Is the cloud secure?
Cloud providers make huge investments into their cloud platforms to ensure availability, and security makes up a huge part of this investment - both digital and physical. Most businesses could not afford this level of security for their offices or server rooms, which makes the cloud far more secure than the alternatives. Choose a UK data centre that is ISO certified and BSI audited to ensure that  the security of your data and applications adheres to British Standards.

6. What should businesses be looking for in a cloud provider?
Businesses should be looking for cloud providers that can offer them capacity to grow, room to scale and resilience. Look for a cloud provider that can work in true partnership with you, rather than just as a supplier. You need to really get to know the people who are operating and supporting your cloud, and likewise they need to understand your business inside out so that they can make strong recommendations that future proof your business.

7. What is hybrid cloud?
Hybrid cloud uses a mesh of public and private cloud infrastructures as part of a bespoke overall platform or solution. These are often complex environments utilising multiple vendors/suppliers.

8. What is multi cloud?
Similar to hybrid cloud, multi-cloud is the term used when an organisation uses two or more cloud platforms, depending on their particular needs. For example, a company could be using Microsoft Azure and AWS to deliver different elements of a solution. 

9. Are there any downsides to cloud computing?
If you choose the right technology and the right partner to build a solution that is fit for purpose, then there shouldn’t be any downsides to moving your infrastructure to a cloud platform. If you get the procurement process wrong, then as with anything, there will be obvious downsides, but if you go in the right direction with the right cloud provider, there is no reason why a cloud solution would present any downsides. 

10. Is cloud computing right for all businesses?
There are many different types of cloud, and many different types of business, so it’s very difficult to say as a generalisation, whether cloud computing is right, or wrong, for a business. Cloud is all about sharing flexible resources, and it’s difficult to see how that wouldn’t be beneficial for any business, but it’s important and necessary that companies find a cloud provider that can work with them, to understand their needs and ascertain which cloud solution, if any, is right for them.
