Earlier we used to store our data in hard drives on a computer. Cloud Computing
services have replaced such hard drive technology. Cloud Computing service is nothing but
providing the services like Storage, Databases, Servers, networking, software’s etc through
the Internet. In our daily routine we use this cloud service without our notice like web-based
email service, watching movies through the internet, editing documents, storing pictures etc
uses cloud computing on the back-end.Using such cloud technology we can design and create
new applications, store and recover data, hosting the websites etc.When choosing a cloud
platform, business owners and decision makers often look only at the cost, while neglecting
many small but essential differences between cloud platforms that may be vital when
choosing the best systems for your business. Cloud services is a rapidly growing market.
Modern technologies like big data analytics, IoT, artificial intelligence and even web and
mobile app hosting all need heavy computing power. Cloud computing offers enterprises an
alternative to building their in-house infrastructure. With cloud computing, anybody using the
internet can enjoy scalable computing power on a plug and play basis.Cloud computing is
usually described in one of two ways. Either based on the cloud location, or on the service
that the cloud is offering.
Based on a cloud location:
Public cloud-The whole computing infrastructure is located on the premises of a cloud
computing company that offers the cloud service. As public clouds use shared resources, they
do excel mostly in performance, but are also most vulnerable to various attacks.
Private cloud-Using a cloud infrastructure (network) solely by one customer/organization. It
is not shared with others, yet it is remotely located. If the cloud is externally hosted. The
security and control level is highest while using a private network.
Hybrid cloud-Using both private and public clouds, depending on their purpose. For
example, public cloud can be used to interact with customers, while keeping their data
secured through a private cloud.
Community cloud-Implies an infrastructure that is shared between organizations, usually
with the shared data and data management concerns. For example, a community cloud can
belong to a government of a single country.
Based on a cloud Service:
Infrastructure as a Service (IaaS) is a cloud model which allows organizations to outsource
computing equipment and resources such as servers, storage, networking as well as services,
such as load balancing and content delivery networks. IaaS is the most flexible cloud
computing model and allows for automated deployment of servers, processing power,
storage, and networking. IaaS clients have true control over their infrastructure than users of
PaaS or SaaS services. The main uses of IaaS include the actual development and deployment
of PaaS, SaaS, and web-scale applications. The most well known IaaS provider, Amazon
Web Services, offers a variety of options, including their “EC2” computing platform, and
“S3” storage platform.
Platform as a Service (PaaS) is a cloud model designed for software developers that
streamlines the development process by shifting specific aspects of systems management to
the service provider. PaaS is used to develop web and mobile applications. What developers
gain with PaaS is a framework they can build upon to develop or customize applications.
PaaS makes the development, testing, and deployment of applications quick, simple, and
cost-effective. With this technology, enterprise operations, or a third-party provider, can
manage OSes, virtualization, servers, storage, networking, and the PaaS software itself.
Enterprises benefit from PaaS because it reduces the amount of coding necessary, automates
business policy, and helps migrate apps to hybrid model. Apprenda is one provider of a
private cloud PaaS for .NET and Java. Examples of PaaS providers include Heroku, Google
App Engine, and Red Hat’s OpenShift.
Top Cloud Platforms:
Software as a Service (SaaS) is a cloud model that delivers on-demand applications that are
hosted and managed by the service provider and typically paid for on a subscription basis.
SaaS is very similar to the old thin-client model of software provision, where clients, in this
case usually web browsers, provide the point of access to software running on servers. Most
SaaS applications can be run directly from a web browser without any downloads or
installations required, although some require plugins. Popular SaaS offering types include
email and collaboration, customer relationship management, and healthcare-related
applications. Some of the most well known SaaS solutions are Google Apps, Salesforce.com,
and Microsoft Office 365
Cloud Computing Platforms:
Amazon Web Services
Amazon’s cloud offering is called Amazon Web Services (AWS) and it was the first of the
major players to offer cloud services to the public in 2006. It makes up about 9 percent of
Amazon’s sales.AWS is the giant of public cloud computing. Amazon was quick to spot the
enormous potential of the cloud as a whole, and so invested heavily in developing an
extensive infrastructure in order to offer the best and most reliable service possible.Because
of its scalability and the billing options that come along with such scalability, AWS is used
by small businesses and huge enterprises alike. Large corporations like Netflix, Expedia and
Adobe all use AWS because it offers a dependable and secure solution. The company offers
an extensive range of IaaS and PaaS services, including its Elastic Compute Cloud (EC2),
Elastic Beanstalk, Elastic Block Store (EBS), Simple Storage Service (S3), Glacier storage,
DynamoDB NoSQL database and Relational Database Service (RDS). Major services that
AWS announced this year include ElasticTranscoder, OpsWorks,CloudHSM, AppStream,
CloudTrail, WorkSpacesand Kinesis. Amazon Web Services (AWS) is the undisputed market
leader in cloud computing. According to Amazon's most recent quarterly financial report,
AWS generated $2.9 billion in revenue for the quarter ending June 30, 2016, up from $1.8
billion during the same quarter last year.
Microsoft also offers the full spectrum of IaaS, PaaS and SaaS services to its customers. The
company was caught napping when it came to its core Windows operating system and its
migration to the smartphone, so it is certainly good news from their investor’s standpoint that
they have managed to carve out a good percentage of the cloud market. its unmatched
commitment to developing and assisting customers to deploy Blockchain, Machine Learning
(ML), and Artificial Intelligence (AI) in innovative production environments, as well as its
market-leading revenue, have allowed Microsoft to remain at the head of the heap. Microsoft
has continued to deliver robust operational performance since Satya Nadella took over as
CEO in 2014. The Azure platform, the firm’s public cloud service, has played a pivotal role
in establishing the brand as the number one player in the space. The company has previously
said that its Azure business is on a $10 billion annual run rate, or around $2.5 billion in
revenue per quarter. Most market analysts put it in the number two spot behind Amazon.
Oracle and Microsoft partnered to bring Linux, Java, WebLogic and Databases to Windows
Azure. Microsoft also invested in data centers in China to add additional regions to Asia
Pacific. Overall, Microsoft made good progress to transform into a mature, enterprise cloud
Google Cloud Platform
Google’s Cloud Platform competes with AWS in every main area of public cloud. Thanks to
global domination of their Android system, the company has been able to covertly introduce
its users to its cloud system through their phones and tablets. Google offers a very full range
of IaaS and PaaS services that span compute, storage, networking, big data, machine learning,
developer tools and security. Some of its best-known cloud offerings include Compute
Other Cloud Platforms
Engine, App Engine, Container Engine, Cloud Storage and BigQuery. Its years of experience
with Gmail, YouTube and Google Drive, and its focus on new AI tools and energy efficiency
means it is likely to soon match Amazon and Microsoft in its caliber of cloud offerings. Its
latest announcement of new data centers in Taiwan and Singapore indicate that GCP will be
soon available in Asia. Google doesn't break out its cloud computing numbers, so it’s very
difficult to tell how much revenue its Cloud Platform generates. In a recent
report, Synergy estimated that Google is fourth in the IaaS and PaaS market with a 4 percent
share of the market.
IBM has always chased the big business market and to be honest, by most indications they
seemed to have followed the same approach with their cloud platform. The company is
particularly focused on PaaS and SaaS cloud systems. IBM's most visible cloud service is its
Bluemix PaaS, which is aimed primarily at enterprise development teams. The company also
a lot of enterprise software on a SaaS basis, and it sells cloud infrastructure, cloud
management tools and cloud managed services. IBM wants to bring AI and IoT closer in
order to deliver unique applications to industry verticals including automotive, healthcare and
manufacturing. IBM also announced its partnership with 21Vianet in China. IBM's cloud
business has been coming on strong. In its most recent quarterly report, IBM said that its
"cloud-as- a-service revenue was up 50 percent," and had an annual run rate of $6.7 billion.
Oracle offers a really respectable range of IaaS, PaaS and Saas services. Particularly notable
is their RightNow suite of applications, which are excellent tools that are designed to
facilitate web, social and contact center customer services while being deliverable across
multiple channels. This suite includes access to live chat features, email support, case
management, virtual assistants. Oracle Corp., a leading database software vendor, unveiled its
ambitious program in the space of cloud computing in 2015. The company announced its
plan during the Oracle OpenWorld event to expand its portfolio in analytical cloud services,
cloud applications Oracle is trying to compete with Salesforce, SAP, Amazon, Google and
Microsoft with its one-size- fits-all cloud platform. This led the company recently reporting a
cloud generated income of $1.2 billion for the first quarter of 2017, an increase of 73% from
a year earlier.
VMWare vCenter Server is a cloud system that allows you to manage virtual infrastructure
by centralizing it all under one roof. VMware is a powerful tool when it comes to improving
the efficiency and effectiveness of your company. VMware entered the cloud space with its
innovative cloud platform, allowing customers to securely deliver access to data and
applications for their end users from multiple devices.VMware recently partnered with AWS,
the online giant’s cloud computing arm, to provide clients with a more integrated solution.
Dreamforce was a big show of power from the SaaS leader, Salesforce.com. If AWS is king
of IaaS, SFDC is undoubtedly the SaaS leader. Salesforce1 aims at simplifying web and
mobile development that unlock the power of data that exists within force.com platform.
founder Marc Benioff is CEO needs to crank up the genius machine and hammer his way into
top contention as a platform powerhouse.
SAP has what all of the other cloud vendors would kill for: unmatched incumbency within all
of the world is leading corporations as the supplier of mission-critical business applications
that run those companies. Plus, SAP's HANA technology is now in full deployment across
thousands of businesses
