This is an
excerpt from the book
WebLogic Multitenancy: WebLogic as a Platform & Foundation
for Cloud Services by Martin Heinzl.
Beside the very common IaaS
(infrastructure), PaaS (platform) and SaaS (service) there
are a number of others "*aaS" service offerings known in our
industry. Some of them are still niche offerings and
emerging others already better established.
This section only wants to name some
of them as examples. There are more out there and new ones
are appearing.
Monitoring as a Service (MaaS)
Every application, especially
production environments - need a reliable monitoring and
alerting. Many service provider - especially in the SaaS
area but also in the PaaS area - offer this service to get
business values, throughput values, non-functional
requirement values for the applications and also to generate
alerts on certain conditions
High Performance Computing as a Service (HPCaaS)
High Performance Computing as a
Service is a service around high performance computing. This
services basically offers a grid as a service for high
performance and highly parallel computing requirements.
Database as a Service (DBaaS)
This basically only offers the
database as a service.
This could either be part of PaaS or PaaS provider
can offer this as an additional services.
In case of an application uses IaaS for whatever
reasons but would like to service out the database to a
provider DBaaS could be a nice offering as well. But
customers should take into in account, that there will be a
noticeable network latency. This limits the possible
scenarios, but does not always make them impossible.
Backup as a Service (BaaS)
A very important service for all
applications.
Which application or platform nowadays could live without
backups? Backup
and restore based on certain SLAs (service level agreements)
are vital services for all applications. Instead of building
an own service it would be better to use available services.
It also is a huge advantage, if you store backups away from
your servers. In case of any disaster, you have a reasonable
chance not losing your business critical data completely. It
is recommended to practice disaster recoveries on a regular
bases.
Communication as a Service (CaaS)
Not the CaaS definition used at the
beginning of the chapter is meant here. Communication as a
service means outsourcing infrastructure like VoIP or even
emails or social networking to a standard service.
Data Intensive Computing as a Service (DICaaS)
This is a special service for dealing
with very large amount of data. This is very common for
scientific institutes.
