Maestro Front-End and Native UI




Maestro front-end is written in Angular 6, an open-source JavaScript-based framework for web application development. Angular 6 was chosen as a flexible framework supporting component approach - if one of the components fails, this does not affect the rest of the system.

As the previous versions of EPAM Orchestrator were written in Angular JS, it was only logical to continue with Angular 6 as such approach could speed up the application development by reusing the already developed elements with certain adaptations. In addition, Angular 6 allows creating dynamic items, for example, by supporting the drag-and-drop functionality featured in Maestro UI.

The mobile Maestro application written in NativeScript based on Angular 6, can be used on Android and iOS without any special adaptations. Angular 6 supports backward compatibility, therefore, Maestro components can be easily integrated with other web applications.


Finally, let's look briefly "under the hood" of the Maestro user interface. In Maestro, the front-end part involves Amazon CloudFront, a content delivery network which receives the hyperlink from the browser and delivers the HTML stored in the special S3 storage. This HTML is a single-page application written in Angular 6 which represents the Orchestrator UI. When another request is made from the UI, only the affected segment of the page is updated, which increases the response and efficiency.

Maestro Analytics: Essentials at the Fingertips

Image
Infrastructure analytics is one of the cornerstones for effective cloud management. Each cloud provider offers its own set of features and services for such purpose. We can say that AWS QuickSight, Google Data Studio, and Microsoft BI are among the top of the native analytics and BI offerings. They are deeply integrated into their native infrastructures, provide the detailed review of the infrastructure state, events and cost, and allow to take a deep dive into details, being powered by strong internal mechanisms and AI/ML engines. However, in many cases they provide a huge volume of data which needs a BI expert to cope with, as well as may have limited customization possibilities in terms of the covered data scope. Also, if you use more than one cloud, or have private datacenters, the fact that each of these tools is limited to its vendor, may be a reason for you to find a third-party analytics tool. Here is where you may consider solutions such as CloudHealth, AppOptics, or IBM C...

Maestro Orchestrator: Product? SaaS? Framework!

Image
In 2012, EPAM Cloud Orchestrator was created as a cloud solution for the EPAM Systems community. It appeared when the issue of redesigning the growing infrastructure of more than 500 projects became critical. After a thorough analysis of the existing solutions, EPAM experts had to admit that none of them fit the company needs. However, that was not a problem but a challenge. If no perfect solution existed, EPAM created its own from scratch. In six years, EPAM Cloud Orchestrator evolved into a true hybrid cloud with over 8000 virtual machines in hundreds of projects. In addition to its basic function - hosting virtual resources - it supports a number of related components helping the users to be in full control of their virtual infrastructures, such as audit, monitoring, billing, reporting. Meanwhile, a time has come to go out of the box of an enterprise solution and meet the market. This is how the new generation of EPAM Cloud Orchestrator - Maestro was born. Maestro is ...
