PaaS: Basic Concepts and Terminology<\/h2>\n

A cloud computing service model that provides a platform allowing customers to develop, run, and manage applications<\/a> without dealing with the complexities of infrastructure management.<\/p>\n

Here are some basic terminologies:<\/p>\n

1. Cloudlets<\/h2>\n

Cloudlets<\/a> are a small building block of platform infrastructure. It is like a particular resource unit providing a specific amount of memory (equivalent to 128 MiB) and processing power (equivalent to 200 MHz). This level of resource detail helps the system allocate just the right amount of capacity for each task or application in the environment. This ensures user-based pricing<\/a>, so that users need to pay only for the resources used.<\/p>\n

\"Cloudlets\"<\/a><\/p>\n

There are two main Cloudlets in our platform:<\/p>\n

Reserved Cloudlets:<\/h3>\n

These are resources you reserve in advance, regardless of whether you end up using them or not. The more you reserve, the more significant discount you get. It\u2019s like booking your seat at a concert ahead of time.<\/p>\n

Dynamic Cloudlets:<\/h3>\n

These resources are automatically added or removed based on your real-time usage. So you only pay for what you end up using, like paying for rides on a trip based on how many you take.<\/p>\n

\"Reserved<\/a><\/p>\n

2. Container<\/h2>\n

In our platform, a container represents an isolated virtualized instance provisioned specifically for handling software stacks such as load balancers, databases, application servers and more. Each container operates independently, offering a secure and isolated environment for running applications or services. Containers are designed to be lightweight and portable, enabling seamless deployment across different environments. One can scale the application both horizontally<\/a> and vertically<\/a>, making hosting of applications truly flexible.<\/p>\n

\"Containers\"<\/a><\/p>\n

Our platform offers certified containers<\/a> for Java<\/a>, PHP<\/a>, Ruby<\/a>, Node.js<\/a>, Python<\/a>, Go<\/a>, and .NET<\/a>. Users also have the flexibility to deploy custom Docker<\/a> containers. Each container is securely isolated and comes with its own private IP address and unique DNS record. Public IPs<\/a> can be easily attached via the UI dashboard or API, simplifying external access configuration.<\/p>\n

\"Custom<\/a><\/p>\n

3. Layer<\/h2>\n

Layer, also termed as a Node group, comprises a cluster of homogeneous containers within a unified environment. Our platform provides a selection of pre-configured layers accessible through the topology wizard<\/a> for certified containers, such as:<\/p>\n
