Versatile Availability Choices (VAC) is a Google Cloud
Platform (GCP) feature that allows customers to choose the best availability
zone for their workloads based on their specific needs. VAC provides a variety
of choices, including:
Regional availability zones: These zones are located in
different regions around the world, providing customers with the ability to
distribute their workloads across multiple locations.
Zonal availability zones: These zones are located within a
single region, providing customers with the ability to place their workloads in
a specific location.
High-availability zones: These zones are designed for
workloads that require the highest levels of availability, providing customers
with redundant infrastructure and multiple paths of connectivity.
VAC also provides a variety of tools and services to help
customers manage their availability choices, including:
The VAC console: The VAC console allows customers to view
their availability choices and select the best zones for their workloads.
The VAC API: The VAC API allows customers to
programmatically manage their availability choices.
The VAC CLI: The VAC CLI provides customers with a
command-line interface for managing their availability choices.
VAC is a powerful tool that can help customers to improve
the availability, performance, and cost-effectiveness of their GCP workloads.
Here are some examples of how VAC can be used:
A customer could use VAC to distribute their workloads
across multiple regions in order to improve the availability of their
application.
A customer could use VAC to place their workloads in a
specific zone in order to reduce latency.
A customer could use VAC to place their workloads in a
high-availability zone in order to meet their compliance requirements.
VAC is a flexible and powerful tool that can be used to meet
the availability needs of a wide range of customers.
Types of A-Versatile Availability Choices
There are three main types of Versatile Availability Choices
(VAC) on Google Cloud Platform (GCP):
Regional availability zones: These zones are located in
different regions around the world. Each region is independent, with its own
infrastructure and power grid. This makes regional availability zones a good
choice for workloads that need to be highly available and accessible to users
around the globe.
Zonal availability zones: These zones are located within a
single region. They share the same infrastructure and power grid, but they are
physically isolated from each other. This makes zonal availability zones a good
choice for workloads that need to be highly available within a specific region.
High-availability zones: These zones are designed for
workloads that require the highest levels of availability. They have redundant
infrastructure and multiple paths of connectivity. This makes high-availability
zones a good choice for workloads that support critical business applications
or that have strict compliance requirements.
In addition to these three main types of VAC, there are
also a number of specialized VAC types, such as:
Nearline zones: These zones are designed for workloads that
need to be highly available and durable, but that do not need to be accessed as
frequently as workloads in regional or zonal availability zones. Nearline zones
are a good choice for workloads such as data archival and backup.
Coldline zones: These zones are designed for workloads that
need to be stored for long periods of time, but that do not need to be accessed
as frequently as workloads in nearline zones. Coldline zones are a good choice
for workloads such as data archiving and long-term backup.
Preemptible zones: These zones are designed for workloads
that can be interrupted without impacting business operations. Preemptible
zones offer significant cost savings, but they are not a good choice for
workloads that require high availability.
Customers can choose the VAC type that best meets their
specific needs. VAC can be used to improve the availability, performance, and
cost-effectiveness of GCP workloads.
Here are some examples of how the different types of VAC
can be used:
A global e-commerce company could use regional availability
zones to distribute their web application across multiple regions. This would
improve the availability of the application and make it accessible to users
around the globe.
A financial services company could use zonal availability zones
to place their trading platform in a specific region. This would reduce latency
and improve the performance of the platform.
A healthcare company could use high-availability zones to
place their patient records system. This would ensure that the system is always
available and that patient records are always accessible.
A media company could use nearline zones to archive their
video content. This would provide a highly available and durable storage
solution for the video content.
A research organization could use coldline zones to store
their research data. This would provide a cost-effective storage solution for
the data.
A startup could use preemptible zones to run their batch
processing jobs. This would allow them to save money on their cloud computing
costs.
VAC is a powerful tool that can be used to meet the needs of
a wide range of customers.
