Template

Templates are used to name machines created on a cloud type and zone along with machine type and image, if available. Once created, a template can be applied while adding an Instance of a Compute option.

Template is organized by Name, Cloud Type, Zone, Machine Type and Image

  • Template Name is a unique name used for identification.
  • Cloud types are Amazon and Azure(Microsoft).
    1. Depending on the Cloud provider, Zone and Machine Type options are shown. If a particular Machine Type or Zone is preferred, that could dictate the choice of Cloud Type.
    2. Another factor that could dictate the choice of Cloud Type is pricing, performance and availability of the desired Machine Type.
    3. If your company already has setup machines in one or more of the Cloud Types, it is good to add those here for creating them, when needed.
  • Zone refers to the location of the data center where the data is stored. Having Compute Instance in proximity to Disks and Network zones could be helpful for delivering better performance, in general.
  • The availability of Machine Type differs based on the Cloud Type provider and Zone selected. They could have different configurations of processors and memory settings, thereby delivering different levels of performance. Some types could be pre-installed with application software.

 

Cloud Provider Machine Type ($) Information Recommendation
Amazon T2.micro / small / medium / large

 

 

Moderate baseline performance with capability to burst to higher performance. Low cost.

 

 

Use for general purpose web servers, development environments, small databases
Amazon M4.large / xlarge Latest generation of general purpose instances with storage optimized at no additional cost Good choice for many applications.
Google F1-micro Offers bursting capabilities to use additional CPU for short periods, comes with 1 virtual CPU, 0.60 GB of memory, backed by a shared physical core. For applications where CPU spikes can occur periodically, where CPU performance is not required
Google G1-small Offers bursting capabilities to use additional CPU for short periods, comes with 1 virtual CPU, 1.70 GB of memory, backed by a shared physical core. Compute units are guaranteed. For applications with constant CPU usage and periodic spikes
Google N1-highcpu-16 / 8/ 4/ 2 High-CPU machine types have 0.90 GB of RAM per virtual CPU. For tasks that require more virtual CPUs relative to memory.
Google N1-highmem-16 / 8/ 4/ 2 High-memory machine types have 6.50GB of RAM per virtual CPU. For tasks that require more memory relative to virtual CPUs
Google N1-standard-16 / 8/ 4/ 2/ 1 Suitable for tasks that have a balance of CPU and memory needs Use for applications

Add Template

Add Template shows options to name it, select a machine type and select an image.

Template - Add Azure
Template – Add Azure
Template - Add Amazon
Template – Add Amazon

Machine Type (based on cloud selection) allows us to select from system types offered by the cloud provider.

Template - Add Azure - Types
Template – Add Azure – Types
Template - Add Amazon - Types
Template – Add Amazon – Types

Select Image lists the images available for the cloud provider.

For Azure, Images can be searched by different options like region (zone), vendor (Microsoft, RedHat, etc.), and version.

Template - Add Azure - Search Images
Template – Add Azure – Search Images

In case of Amazon, Images are organized by Platform, Architecture, and Volume Type apart from Zone.

Template - Add Amazon - Select Image

Template – Add Amazon – Select Image

  • Image usually refers to a point in time configuration of a system. It could have a certain set of patches/programs configured so as to meet certain processing requirements. Rather than repeat configuration steps on new systems being created, saved images can be used to create a new system.
  • Platform refers to the Operating System type installed on the image

 

Platform Information Cloud Platforms
CentOS The CentOS Linux distribution is a stable, predictable, manageable and reproducible platform derived from the sources of Red Hat Enterprise Linux (RHEL). Since March 2004, CentOS Linux has been a community-supported distribution derived from sources freely provided to the public by Red Hat. As such, CentOS Linux aims to be functionally compatible with RHEL. We mainly change packages to remove upstream vendor branding and artwork. CentOS Linux is no-cost.
