If you are contemplating hosting some of your applications and data in one of the large public clouds, you are probably wondering what the performance and availability is like.
Up to now, the only way has been to trust the vendors claims or to sign-up to the services and test them yourself.
If you are considering hosting your application(s) with a cloud service provider …. read this first.
PaaS is an acronym for Platform as a Service.
PaaS is an outsourced service offering in which a service provider hosts all the infrastructure services that you are likely to need, such as database management, application serving, development environment, workflow and security. Using these services, you can either develop your own business system or deploy a ready-built one.
Typically, the infrastructure will be delivered using virtual infrastructure which allows the service provider to better utilise hardware and hence offer the service at a lower cost than the traditional ‘host your own servers’ method.
“Shared computing resources that can be dynamically scaled according to business requirements, faster than traditional computing environments.”
It’s easy to come-up with a one line description, but what does it mean and why is there so much hype about cloud computing? The term ‘cloud computing’ has been in use for some years now, but is now getting increased publicity as it enters the mainstream.
Generally, when people refer to ‘Cloud Computing’, they are referring to rented computing services from a service provider, accessed across the internet. Using this service means the client needs less IT infrastructure on their own premises and reduced costs because the underlying infrastructure is shared between many clients.
