Bring together the different forms of cloud computing with the hybrid approach
A recent study predicted that an increasing share of the IT budget will migrate capacity on site to the off-site services, such as computing and hosted public cloud. While this development seems inevitable, it will be gradual and hybrid cloud computing will play the role of bridge between these two service deployment models.
Many companies have invested heavily in their technology on-site and often budgeted two or three years of depreciation costs which should make their profits. So despite all the attraction of the public cloud, companies prefer to operate their own IT resources until amortization is no longer recognized as a benefit in the income statement.
The advantages of hybrid cloud
This is where the hybrid cloud. Combining the opportunity to achieve greater use of technological resources on site and the flexibility to exploit the advantages of the public cloud in terms of cost and agility, it will become essential to reach the next level of technology services business .
Commissioned by Microsoft and conducted by 451 Research, the 2014 study on cloud computing and hosting interviewed more than 2000 companies on their strategy and spending on cloud computing. Today, 41% of the IT budget of companies that responded is dedicated to data centers or sites they manage themselves, against 59% spent on outsourced services, collaboration, SaaS and PaaS. In two years, they expect that the distribution is 38% against 62%.
The information to remember is that the hybrid cloud is gradually establishing itself as the essential model for corporate users.
It seems that the reason for such popularity is twofold. On the one hand, many companies still have an investment in the equipment on site, required for specific tasks. Moreover, accommodation in the public cloud provides the scalability and flexibility that do not offer the purchase and maintenance of equipment. The hybrid cloud computing is the intersection between.
Users of hybrid cloud
There are many use cases of the hybrid cloud there are users; it can include any number of infrastructure blocks distributed between the public cloud, private cloud, colocation and site servers.
According to a report by consulting firm and technology studies TechNavio, the hybrid cloud market was worth 21.18 billion dollars in 2013 and will reach 79.12 billion in 2018. Also according to this study, the main drivers of market will remain the same so far, namely: reduce IT costs, improve business productivity and implement regulatory policies and strict security.
The experience of the cloud computing industry seems to confirm these findings. The Australian telecommunications operator Telstra is currently taking a new strategic direction, extending the systems integration services in the United States. Erez Yarkoni, Executive Director in charge of cloud computing, refers to the common profile for most of its customers.
“We see the mega-infrastructure in the public cloud and emerging business such as SoftLayer cloud, but also automated infrastructure facilities on site. All our customers are somewhere in the middle and it will be so for long. ”
Surprisingly, this applies both to large companies or governments at the SMB market.
“They say they need their own private applications or their basic access to localized data, they really can not move to a public cloud,” adds Erez Yarkoni.

What then are the advantages of a hybrid cloud approach for users, when it seems much easier to maintain and execute all processes in one place?
“There are always compromises,” admits David McKnight, Director of Operations for Leisure Interactive, a provider of POS systems, property management and online reservations. “The key is to define what compromises add value.”
In his case, the hybrid approach is a safety issue. Microsoft Azure was suitable for most systems, except one: the storage of encrypted data of customers’ credit cards, which could not be hosted in a public cloud environment. With 50 million transactions in 2013, Leisure Interactive had no choice but to accommodate the separate payment system of the reservation system in order to comply with the Payment Card Industry (PCI ).
When a booking is made on the company’s website that is hosted in a public environment, the payment is processed via a connection to a payment gateway, the details are stored in the private cloud Leisure Interactive. Although Microsoft announced Azure PCI compliance in early 2014 and that David McKnight studying the issue, the financial data are for many a common barrier to a fully public cloud service.
In another case, a private cloud is the best solution for a specialized workflow, while other applications can run in public environments. Kris Kelso, IT strategy consultant, has among its clients a production company / marketing that originally housed most of its systems either internally or in shared accommodation. After an analysis of return on investment, he helped this company to transfer most of its systems oriented customers to Amazon Web Services, apart from a crucial function.
