No1 Platform as a Service (PaaS) Hosting Solution

In our PaaS, resources are measured in cloudlets – a special measurement unit, which includes 128 MiB of RAM and 400 MHz of CPU power simultaneously.

Being highly granular, it allows to accurately determine the required capacity for each server in environment, which ensures the truly fair usage-based pricing so you do not overpay for the unused resources.

Reserved & Dynamic Cloudlets

There are two types of cloudlets in our PaaS, available to be setup for every server in environment via the Vertical Scaling per Node topology wizard section: Reserved and Dynamic.

Herewith, if a layer contains multiple nodes, these limits are configured for all of them at once, i.e. are stated equal for each instance.

Here, each toddler corresponds to a particular cloudlet type:

• Reserved Cloudlets – these ones are reserved in advance and will be charged irrespective of your actual resource usage. In exchange, you’ll get significant automatic discounts based on their number.

• Dynamic Cloudlets –are added & removed automatically according to the amount of resources that are required by your application in a particular moment of time – i.e. they’re assigned when load goes up and removed again as soon as it drops down. As a result, you pay based on your actual resource usage.

  

  This type of cloudlet helps to cope with unexpected surges in demand without any pre-planning, special coding or overpaying for resources you won’t need the majority of time. In such a way, with the Dynamic Cloudlets slider you set the container’s Scaling Limit, defining the maximum possible number of cloudlets available to be allocated for it.

  In order to gain the maximum profit, it is recommended to use Dynamic Cloudlets alongside with the Reserved Cloudlets to get all the advantages of your application’s automatic vertical scaling and, simultaneously, to benefit on automatic discounts.

  Cloudlet Consumption Calculation

  Number of used cloudlets is calculated on hourly basis in the following way:

  • for RAM – the peak value (i.e. the highest RAM consumption over the hour)
  • for CPU – the average usage

    The greater of these values (but not both of them combined) is considered as the actual environment consumption, which will be charged from your account according to the provider’s tariff.

    For example, if during one hour your average CPU usage is 2400 MHz (6 cloudlets), and your highest RAM usage is 1024 MiB (8 cloudlets), you’ll be charged for 8 cloudlets only – not for the combined total of 14 units.

    Consumption Tracking

    The current resource usage of your environment in general and for every layer/node it comprises in particular can be seen within the corresponding Usage column at dashboard:

    

    And in order to review your servers’ consumption level for a particular period of time, you can use the corresponding Statistics section or check the applied account charges within your Billing History.

IaaS PaaS and SaaS are all crucially important for the business world.

However, depending on your business’s industry and type you may only benefit from IaaS and SaaS. For example, a company in the Foods & Beverages industry can definitely benefit from hosting its website through IaaS and could definitely benefit from various SaaS applications, such as Salesforce.

On the other hand, it is natural for some types of software and application development businesses to rely on IaaS and PaaS, or even solely on PaaS. Especially software and application development startups have a lot to gain from exclusive PaaS utilization, in terms of cost-efficiency, productivity and speed to market.

However, this strategic decision should include the consideration of the quality of the chosen PaaS Provider. Specifically, startups which have limited resources and need to have increased adaptability to achieve quick and reliable application and software development, should not choose a third-party vendor. PaaS resellers have no access to the cloud infrastructure and an unnecessary organisational level is added, eventually affecting resolution times, communication and overall productivity.

For this type of startups it is necessary to work with a high-availability PaaS provider, whose cloud infrastructures have no single points of failure. This will truly allow your new project to stand on a steady, fruitful ground from which to build towards success.
