Cloud Service Level Agreements (SLAs)
It is important to understand
that when any kind of cloud services are provided to customers, then there
should be a service level agreement between the customer and the provider to
maintain a minimum level of service. It is essential to do so because customers
want some guarantee from the service providers that they will ensure a good
level of service in different given situations. There can be various points,
which can be made part of the SLAs. For instance, one point in the SLAs can be
stated as “Provide for disaster recovery
and continuity of operations planning and testing, including how and when the
cloud service provider is to report such failures and outages to the agency. In
addition, how the provider will remediate such situations and mitigate the
risks of such problems from recurring” It means that it is the
responsibility of the cloud service provider to maintain good service levels
and if any risks or issues have occurred, those should not happen again (Cooney, 2016)
It is a fact that when any cloud
service provider provides services, there can be some issues, which are out of
control, and those issues cannot be used to hold the service provider
responsible for anything. It means that while mentioning SLAs, such limitation
should also be mentioned in the document. Microsoft Azure is one of the famous
cloud services, and in their cloud SLAs, they have mentioned limitations, where
SLAs will not be applicable to certain issues such as “Due to factors outside our reasonable control (for example, natural
disaster, war, acts of terrorism, riots, government action, or a network or
device failure external to our data centers, including at your site or between
your site and our data center)”. They have also mentioned so many terms in
their SLAs document, which should be considered by the customer while getting
their services. In terms portion of the SLAs document, Microsoft Azure provider
has mentioned any claims that “For a
claim related to Microsoft Azure, we must receive the claim within two months
of the end of the billing month in which the Incident that is the subject of
the claim occurred. For claims related to all other Services, we must receive
the claim by the end of the calendar month following the month in which the Incident
occurred” (Microsoft Azure, 2017)
It is important for companies or
individuals to look for a few things in SLA, who are looking to use any cloud
services. Every service provider comes with different types of SLAs, so it is
vital to look at their SLAs document in detail to decide, which service
provider is providing the best services. As a customer, you should look for a
few things in the SLA. The first thing is availability; it means that what kind
of service is available from the service provider. Moreover, you should also
analyze their SLAs related to cloud software & hardware, as well as, data
ownership. In addition to that disaster recovery, as well as, backup services
is quite crucial to be analyzed, because if service provider ensures good
recovery in case of any issues, then they can be considered a better service
provider. One last thing to look in the SLAs document is customer
responsibility, which has been mentioned by the service provider so that you
understand what is needed on your end (Hein, 2019)
