General Questions

The topic contains the answers for the most typical "What Is?" questions related to EPAM Cloud.

What is EPAM Cloud in general and how does it function?

EPAM Cloud Orchestrator is a part of existing EPAM ecosystem which provides the possibility for project teams to manage virtual infrastructure via a self-service solution.

The key characteristics of EPAM Orchestration Service is its multitenancy, which allows the users who work on different projects to act independently and not to interfere with each other.

What is cloud computing?

Cloud computing is defined as a style of computing in which massively scalable IT-related capabilities are provided 'as a service' using Internet technologies to multiple external customers (Gartner). Beyond the Gartner definition, clouds are marked by self-service interfaces that let customers acquire resources at any time and get rid of them the instant they are no longer needed.

The cloud is not really a technology by itself. Rather, it is an approach to building IT services that harnesses the rapidly increasing horsepower of servers as well as virtualization technologies that combine many servers into large computing pools and divide single servers into multiple virtual machines that can be spun up and powered down at will.

How is cloud computing different from utility, on-demand and grid computing?

Cloud by its nature is "on-demand" and includes attributes previously associated with utility and grid models. Grid computing is the ability to harness large collections of independent compute resources to perform large tasks, and utility is metered consumption of IT services, says Kristof Kloeckner, the cloud computing software chief at IBM. The coming together of these attributes is making the cloud today's most "exciting IT delivery paradigm," he says.

Fundamentally, the phrase cloud computing is interchangeable with utility computing, says Nicholas Carr, author of "The Big Switch" and "Does IT Matter?" The word "cloud" doesn't really communicate what cloud computing is, while the word "utility" at least offers a real-world analogy, he says. "However you want to deal with the semantics, I think grid computing, utility computing and cloud computing are all part of the same trend," Carr says.

Carr is not alone in thinking cloud is not the best word to describe today's transition to Web-based IT delivery models. For the enterprise, cloud computing might best be viewed as a series of "online business services," says IDC analyst Frank Gens.

What is a public cloud?

Naturally, a public cloud is a service that anyone can tap into with a network connection and a credit card. "Public clouds are shared infrastructures with pay-as-you-go economics," explains Forrester analyst James Staten in an April report. "Public clouds are easily accessible, multitenant virtualized infrastructures that are managed via a self-service portal."

What is a private cloud?

A private cloud attempts to mimic the delivery models of public cloud vendors but does so entirely within the firewall for the benefit of an enterprise's users. A private cloud would be highly virtualized, stringing together mass quantities of IT infrastructure into one or a few easily managed logical resource pools.

What is EPAM Orchestrator?

The best answer to this question can be found on What is EPAM Orchestrator? page. If this is not what you are looking for, do not hesitate to ask us directly, we will be glad to describe and explain it to you in most comprehensive manner.

How do I activate a project in EPAM Cloud?

To activate a project in EPAM Cloud, please, submit a Project and Region Activation Request and provide the project ID as is given in UPSA and the name of the region or regions in which the project should be activated. This request should be approved by Project Manager or Project Coordinator.
Please note that the project can be activated only by its UPSA code; customer's name, cost object, and other identifiers cannot be used for project activation.

What to begin with in order to start using EPAM Cloud, CLI Tools?

1. Make sure your project is active in Orchestration: use the or2-describe-projects (or2dpro) --full command or use Audit page of Orchestrator UI.

2. Please visit the Quick Start page for tips on Quick Start or follow instructions in the Maestro CLI Quick Start Guide right away.

Self-Service in Cloud. Is it manageable? How can it be controlled? What are the tools for management?

EPAM Cloud gives managers and engineers an ability to manage and control the existing infrastructure with the help of Web UI and CLI tools. Web UI provides infrastructure monitoring facilities and basic control on the infrastructure resources - running VMs and stacks, changing VMs state. Maestro CLI allows to perform more complicated actions. The operations a user is allowed to perform depend on their Project Role and Cloud Role, set by project manager/project coordinator.
