WHAT IS ORCHESTRATION?


Orchestration, a difficult word, isn’t it? Not many of us have heard this word before cloud computing came in demand. Well let’s try to simplify this difficult word.

Synonyms: Arrange, coordinate, manage, setup, organize, put together, plan, mobilize.

Antonyms: Divide, separate, disorganize, ignore

Did you get it? No? Don’t worry, I have a short article to describe this.

Orchestration is automating tasks on cloud or on premises on large scale. So, does it mean automation, well, not actually, but yes, somewhat it’s the same.

The difference is: 

  • Automation refers to making a single task to run without human intervention 
  • While orchestration refers to automating multiple tasks in a large scale

Definition:

Automation: The definition of automation says to run a single task on its own, this task can be anything like launching an application, starting or stopping a service, communicating with other application or service.

 

Orchestration: The definition says, orchestration includes the automated arrangement, coordination, and management of computer systems, middleware, and services. This refers to automating a lot of things together.


Orchestration takes advantage of automation and executes large workflows systematically.

For example, application orchestrating doesn’t mean only deploying an application, but also connecting it to the network, communicate with users and other apps, auto-scaling in the correct order, with the right security rules and permissions in place and many more.

Usage:

Azure Data Factory, a cloud-based data integration service from Microsoft which allows to create data-driven workflows in the cloud for orchestrating and automating data movement and data transformation.

Control flow is an orchestration of pipeline activities that includes chaining activities in a sequence, branching, defining parameters at the pipeline level, and passing arguments while invoking the pipeline on-demand or from a trigger. It also includes custom-state passing and looping containers, that is, For-each iterators.

Cloud orchestration vendors:

  • Amazon Web Services CloudFormation
  • Cisco CloudCenter (formerly CliQr)
  • CloudFX
  • Flexiant Cloud Orchestrator
  • Fugue
  • IBM Cloud Orchestrator
  • Ingram Micro Cloud Orchestrator
  • Microsoft Azure Automation
  • Microsoft Cycle Computing
  • Morpheus
  • OpenStack Heat orchestration engine
  • Saltstack
  • Zymr

Orchestration software:

  • Ansible
  • Chef
  • Harrow
  • Puppet
  • Terraform
  • Rex
  • Salt
  • Kubernetes

Types of orchestrations:

  • Cloud orchestration
  • Container orchestration
  • Network orchestration
  • Application orchestration
  • Service orchestration

 

Related terms: Containers, Kubernetes, Docker

WHAT IS RAID?

Using Multiple Hard Drives for Performance and Reliability Introduction Back in the late 1980's and early 1990's, computer information servers were encountering a dramatic increase in the amount of data they needed to serve and store. Storage technologies were getting very expensive to place a large number of high capacity hard drives in the servers. A solution was needed and thus RAID was born. So what exactly is RAID? First of all, the acronym stands for Redundant Array of Inexpensive Disks. It was a system developed whereby a large number of low cost hard drives could be linked together to form a single large capacity storage device that offered superior performance, storage capacity and reliability over older storage solutions. It has been widely used and deployed method for storage in the enterprise and server markets, but over the past 5 years has become much more common in end user systems. Advantages of RAID There are three primary reasons that RAID was imp...

IMPORTANCE OF CPU SPEED OR PROCESSOR SPEED AND MEMORY

  Introduction A very common question is, which is more important, the processor speed or the amount memory. This is a difficult question to answer, so we have to understand what each component does and how they relate to each other. This information will strive to teach you the basic tasks of memory and the CPU Central Processing Unit (CPU) It is called the brain of the computer, whose job is to take information from the various input devices, like the OS, software and execute them. A CPU executes a certain amount of instructions within a grouping called a cycle. The speed of the CPU is measured in how many cycles it can perform in a given second. A speed of one cycle per second is called a hertz. This is illustrated in the table below: Hertz Term Cycles Per Second 1 Hertz 1 1 Megahertz 1,000,000 800 Megagertz 800,000,000 1 Gigahertz 1,000,000,000 So it is better to have a very high Speed CPU, as more instructions get executed in one second. In early days normal speed of a CPU is ...
