Deploying and Managing Custom Apps in the Cloud

There is a need to provide a horizontal framework that anyone can use to quickly build a vertical solution

At Kaavo we recognized that there is a need to provide a horizontal framework that anyone can use to quickly build a vertical solution for running and managing their complex custom applications in the cloud. To enable single click deployment and runtime management of any custom application in the cloud Kaavo’s IMOD uses System Definition file for automating complex workflows and dependencies for deployment and runtime management.  Understanding the structure of System Definition file is important to fully benefit from Kaavo’s application centric management approach.

System Definition file is an XML document with support for embedding velocity templates for dynamically generating configuration files, scripts, and workflows in any programming language on the fly during deployment or in response to run-time events.

The system definition file has two main sections, deployment and runtime.   See the figure below for more details.

Deployment section contains information about tiers in the system, we can define 1 or n tiers, in each tier we can have 1 or n resources, each resource can have post startup or pre-shutdown actions or workflows.  We can define the order in which tiers are configured and displayed and group the resources within a tier.  We can also define workflows at the tier level and at the system level.

Runtime section of the system definition file can contain complex custom workflows required for managing the runtime service levels of the application.  Runtime workflows can be custom automation, for example scale up, scale down, auto-recovery or any application specific custom maintenance task, e.g. backup database, run batch jobs, etc.  For more information on please review the N-tier System Definition Guide and the XSD for the System Definition.

WebRTC is great technology to build your own communication tools. It will be even more exciting experience it with advanced devices, such as a 360 Camera, 360 microphone, and a depth sensor camera. In his session at @ThingsExpo, Masashi Ganeko, a manager at INFOCOM Corporation, will introduce two experimental projects from his team and what they learned from them. "Shotoku Tamago" uses the robot audition software HARK to track speakers in 360 video of a remote party. "Virtual Teleport" uses a...
While some vendors scramble to create and sell you a fancy solution for monitoring your spanking new Amazon Lambdas, hear how you can do it on the cheap using just built-in Java APIs yourself. By exploiting a little-known fact that Lambdas aren’t exactly single-threaded, you can effectively identify hot spots in your serverless code. In his session at @DevOpsSummit at 21st Cloud Expo, Dave Martin, Product owner at CA Technologies, will give a live demonstration and code walkthrough, showing how ...
Translating agile methodology into real-world best practices within the modern software factory has driven widespread DevOps adoption, yet much work remains to expand workflows and tooling across the enterprise. As models evolve from pockets of experimentation into wholescale organizational reinvention, practitioners find themselves challenged to incorporate the culture and architecture necessary to support DevOps at scale.
When shopping for a new data processing platform for IoT solutions, many development teams want to be able to test-drive options before making a choice. Yet when evaluating an IoT solution, it’s simply not feasible to do so at scale with physical devices. Building a sensor simulator is the next best choice; however, generating a realistic simulation at very high TPS with ease of configurability is a formidable challenge. When dealing with multiple application or transport protocols, you would be...

As more and more companies are making the shift from on-premises to public cloud, the standard approach to DevOps is evolving. From encryption, compliance and regulations like GDPR, security in the cloud has become a hot topic. Many DevOps-focused companies have hired dedicated staff to fulfill these requirements, often creating further siloes, complexity and cost. This session aims to highlight existing DevOps cultural approaches, tooling and how security can be wrapped in every facet of the bu...
yperConvergence came to market with the objective of being simple, flexible and to help drive down operating expenses. It reduced the footprint by bundling the compute/storage/network into one box. This brought a new set of challenges as the HyperConverged vendors are very focused on their own proprietary building blocks. If you want to scale in a certain way, let’s say you identified a need for more storage and want to add a device that is not sold by the HyperConverged vendor, forget about it....
