In 2006, Amazon.com introduced its
Elastic Compute Cloud product, which popularized cloud computing.
In 1996, Compaq's internal documents
made the first known reference to "cloud computing”.
During the original ARPANET and
CSNET, both precursors to the Internet, the cloud symbol represented networks
of computing hardware as early as 1977. On telephony schematics, a cloud-like
shape denoted a network, and the word cloud is used as a metaphor for the
Internet.
What is
cloud computing
In cloud computing, resources such as data storage
(cloud storage), computing power, and communication capabilities are available
as needed. In large clouds, functions are often distributed among
several data centers. The cloud computing model is based on sharing
resources for coherency and efficiency.
The
widespread implementation of hardware virtualization, service-oriented
architecture, and autonomous and utility computing along with the availability of
high-capacity networks and low-cost computers has created a demand for cloud
computing. As of 2017, 90% of public clouds run on Linux. A cloud
may be limited to a single organization (enterprise or private clouds) or be
available to several organizations (public clouds).
Cloud computing benefits
Cloud computing offers many benefits to
your business. Essentially, it gives you the flexibility to connect to your
business from wherever you are. As more web-enabled devices are used in today's
business world (e.g. mobile phones, tablets), access to your data is even
easier.
1. Cost reductions in IT
Your IT costs may be reduced if you move to cloud
computing. By using the cloud computing service provider's resources, you can minimize the cost of buying
expensive systems and equipment for your business.
2. Affordability
Depending on your needs, your business can adjust your operation and storage needs quickly. If you use a cloud computing service provider, then you don't have to purchase and install expensive upgrades yourself. When you use the cloud, you can focus on running your business instead of spending time on IT.
3. Continuity of operations
A major part of business continuity planning is protecting data and
systems. A cloud-based backup method
ensures your data is protected and backed up in a secure and safe location
during a natural disaster or a power outage. You can conduct business as usual
after you can access your data again quickly, thus reducing downtime and
maximizing productivity.
4. Efficiency in collaborative projects
When your business collaborates in the cloud, traditional
communication methods are easier to discard. Cloud computing can be used to
allow employees, contractors, and investors to access the same files across multiple locations when working on a project. Cloud computing also allows you to
communicate with your advisors quickly and securely (e.g. you could share
accounting records with your accountant).
5. Flexibility in working methods
Work practices are more flexible
with cloud computing. Data can be accessed from home, on vacation, or during travel (if an internet connection is
available). Accessing your data from your virtual office is fast and easy even if you are
off-site.
6. Auto-updates are available
As part of your service fee, you
may receive automatic IT updates. With a cloud computing service
provider, you can have your system regularly updated. Up-to-date software, as
well as upgrades in computer power, could be part of this.
Security for cloud-based systems,
data, and infrastructure encompasses a variety of policies, controls,
procedures, and technologies. Cloud data is protected,
regulatory compliance is supported, customer privacy is safeguarded, and authentication
rules are set for every user and device. The configuration of cloud security
can be tailored to meet the exact needs of a business, including authenticating
access and filtering traffic. The ability to configure and manage rules in one
place means that administration overheads are reduced and IT teams can focus on
other business areas.
Each cloud security solution or cloud
provider will deliver security in its own way. A business owner and solution
provider must work together to implement cloud security. Among
the benefits of cloud security are:
It provides centralized security,
lower
costs, reduced administration,
and high reliability.
