Comparing Public, Private and Hybrid Clouds

The ability to share resources and access files from virtually anywhere and on any device has made cloud environments extremely viable in the eyes of a growing number of organizations and the general public. The “cloud” is essentially a third-party infrastructure that creates a network of machines that store data, allowing for greater flexibility in the way businesses and organizations are able to manage data. The economic advantages of using a cloud computing model are undeniable, but with various deployment models, it is important to first determine the needs of your business so you can choose if a public, private or hybrid cloud is right for you.

The most common model of cloud computing is a public cloud, where data storage is provided and accessible over a public network, like the Internet. Ideal for sharing resources and doing collaborative work, this model is typically provided as a service and is used for applications that have a lot of users. Public clouds also tend to be inexpensive and are usually on a pay-per-usage scale based on capacity, so organizations can still optimize efficiency without the high-added cost. However, because this model is built for collaboration, it offers limited security and reliability. The ease of access and availability of the data stored on a public cloud makes it inadequate for keeping sensitive or confidential information secured.

For greater security and control over a data center, a private cloud offers data storage over a private data network that is owned by a single company. Typically used by larger businesses because of the higher cost, the private cloud computing model offers security through firewall protection and gives the company complete control over information within the data center. For businesses whose assets primarily lie in their data and applications, or for those that operate within a secure industry that handles sensitive information, a private cloud should be a perfect fit.

With a hybrid cloud model, two or more different deployment models operate individually but are united under a single entity, allowing businesses the versatility of being able to manage both private and public data. Hybrid clouds are more complex to manage because they combine both in-house and external storage, but they’re useful in keeping all aspects of the business in their proper environment – secure information is controlled, while collaborative access is allowed to other less sensitive data. Especially for multifaceted businesses and organizations that store a variety of client and company data, a hybrid cloud can provide the flexibility in access necessary to operate under special circumstances.

With evidence of good economies of scale and various fiscal and organizational advantages, knowing which cloud type best meets your needs can make a significant impact on how your business manages data. Which cloud model do you think is right for your business? Let us know in the comments below!

2015: Time to Focus on the Cloud

It is predicted that as of this year, 90% of enterprises will have hybrid cloud services in place. Taken at face value, this sounds as if the battle is over for enterprise IT and the migration to SaaS, PaaS or IaaS is all but accomplished. However, for many IT departments, it simply means they have only begun to fight by migrating at least one software service, such as email, to public infrastructure.

The reality is that integration of cloud services will become the standard, sooner rather than later. Those enterprises that delay adoption, while the trend accelerates, will find themselves mired in an inefficient paradigm of managing in-house compute resources while competitors reap the advantages of flexible and extendible services residing in the cloud.

Benefits of Cloud Migration
Moving to a cloud paradigm spells opportunity for most businesses. The benefits are many:

• Reduction of expenditures in capital equipment
• Ability to rapidly scale compute costs to meet growth projections or point events
• Elimination of maintenance, update and recovery expenses
• An increasingly connected, agile mobile workforce
• Increased security and data control

Cloud migration, however, is not simply a matter of throwing a switch. Like any strategic move, there are tradeoffs. For instance, organizations must weigh the benefits of being able to rapidly respond to their market, with the detriment of giving up some control of application customization.

First Steps to Migration
One universal problem that has plagued IT departments before “cloud” entered the organization’s lexicon is still applicable: what to do with legacy applications. These are built upon assumptions about the environment in which they operate regarding software and hardware platforms, network infrastructure, security and monitoring. This situation leaves IT with an important decision: Should such applications be deployed first to a private cloud or go straight to a public cloud deployment?

Public versus Private Cloud
The decision whether to go private or public is guided by these factors:

• Service Demand – A private cloud is appropriate if demand is predictable and steady. If there is high variance, a hybrid or 100 percent public cloud approach makes sense.
• Network Requirements – Organizations requiring access only via specific networks or vendors cannot take advantage of public cloud services effectively.
• Application Dependencies – Enterprise applications with tight dependencies on specific devices or internal applications have the most difficulty in migrating to public cloud services.

Sub-Hybridization of Apps
IT departments overwhelmed by the scope of changes to analyze and act upon might consider taking smaller steps than wholesale migration of apps and services to any cloud - private or public. Hybridizing a single application in order to retain control over core features, while taking advantage of the flexibility of resources public cloud vendors offer, is one way to do this.

One example where this works is to retain a proprietary database within the organization infrastructure while "virtualizing” the interface to these data on servers located geographically closer to customers. Gradually, remote data caches can be added to improve responsiveness before converting to a fully distributed database.

Delaying Adoption Places You Squarely Behind the Curve
The challenges to moving to a cloud infrastructure are formidable but certainly not insurmountable. Delaying decisions because of lack of knowledge, skills or legacy drags your business behind the surging transition to cloud services. Rather, put your organization’s focus on the long-term benefits:

• Network and device autonomy
• Employee and customer IT self-service
• Resource elasticity to meet changing market demands
• Increased customer touch by a mobile workforce
• Higher collaboration potential among employees

The bottom line is a decrease in overhead and complexity with an increase in business productivity.

2014 Recap of Virtualization Technologies

2014 was another banner year in data center virtualization innovations for storage, networking and integrated resource management. Advances were also made in response to demands for higher security, support for hybrid cloud and virtualization services, and the pervasiveness of enterprise workforce mobility. Here are ten of last year’s most important developments.

1. VMware embraced OpenStack, the leading IaaS (infrastructure-as-a-service) solution in cloud computing for controlling pools of storage, networking and processing resources. Their OpenStack distribution, labeled VMware Integrated OpenStack or VIO, allows customers to migrate to an open source base while retaining the ability to manage through VMware’s vCenter.


2. VMware expanded their leadership in the software-defended data center (SDDC) space via PaaS EVO Rail and EVO Rack hyper-converged infrastructure packages for small and large organizations, respectively. These cross-provider hardware and software packages are designed specifically to streamline deployment in support of SDDC expansion. Already, OEM partners Supermicro, EMC, Inspur, Fujitsu, Dell and Net One Systems Co. are certified to offer single-point integrated systems.


3. Companies are racing to virtualize their mission critical applications and data in the public cloud as they become familiar with new security and privacy solutions. The advantages of dynamic scaling and infrastructure efficiency by utilizing the public cloud for the largest applications has become impossible to ignore.


4. Virtual Desktop Infrastructure made a big leap forward this year in engineering graphics applications. For example, VDI technology from Citrix paired with NVIDIA’s most powerful GPUs and Dell computing hardware allowed Boeing to efficiently design the 787 Dreamliner using a global engineering and design team accessing a single database.


5. Mid-year, VMware brought a new level of capability to VDI and DaaS technology with its release of Horizon 6.0. It supports enterprises that rely on a mix of VDI and non-VDI machines. End-user software is containerized, deployed in the public or private cloud or on the desktop. Users can access enterprise apps via Workspace from any device whether they exist as a public or private cloud service or a desktop application.


6. VMware announced a new suite of products based on a more scalable architecture under the brand name vRealize. This major release allows single-console visibility of an entire enterprise’s network, storage and computing devices plus state-of-the-art analytics, alerts and support for problem detection and remediation.


7. Virtualization within the ‘Internet of Things’ leapt forward in 2014. For instance, Wind River®’s release of a new virtualization profile within its VxWorks® OS supports embedded virtualization by allowing any combination of VxWorks, Windows® or Linux OS to share memory and processing cores.


8. Nearly 100 percent of technology companies have implemented bring-your-own-decive (BYOD) initiatives as of the end of 2014. Furthermore, well over 50 percent of IT companies have identified support for mobility and BYOD as top spending priorities in the years ahead.


9. Network-as-a-Service or NaaS, began a new chapter with the Metro Ethernet Forum’s announcement of a Third Network Initiative based on the forum’s Ethernet 2.0 specification. Service coordination, APIs, network protocol independence and clarity around physical and virtual service endpoints will be included. The goal is to provide on-demand, secure and scalable network service across multiple network providers while meeting existing SLAs.


10. 1As containerization technology grew from a niche into common knowledge, the implementation of virtual micro-services and the architectures to support them went mainstream in 2014. This development is leading to increased economic advantages for both large and small players, especially in mobile cloud and virtualization services.

In the near future, 2014 may be seen as a watershed year for virtualization technologies and services as they become imperatives for IT companies going forward. Keep an eye on 2015 to see how these new developments play out.

5 Steps to Trim Your IT Budget Using Virtualization

Although the concept has been around for decades, the idea of employing virtualization on computers has just recently started gaining serious traction in business. Businesses of all types and sizes are learning the incredible benefits of server virtualization, including:

• The capability of running multiple applications and operating systems on one single computer
• Savings of more than one-half of ongoing IT costs
• Higher productivity as a result of hardware consolidation and the requirement for drastically fewer servers
• Faster deployment of applications, far less IT maintenance and a much simpler IT management system

5 Cost-Reducing Advantages of Virtualization

1. Typical business IT departments spend somewhere around 70% of their budget on maintenance of an ever-growing hardware infrastructure. Because most of today's business computers use an X86 platform, which are designed to run only one application or operating system at a time, more servers must be deployed to satisfy the needs of each data processing center - even though existing systems are typically only being used to about 15% of their computing potential. Creating virtual systems within a computer allows each server to utilize approximately 80% more of its potential computing power, far outpacing the average and inefficient 15% mentioned above.
2. Because the efficiency of each piece of computing hardware is significantly increased, this means the amount of required hardware is substantially reduced through consolidation to about 1/10 of what's required without the introduction of virtualization.
3. A more efficient, simpler and agile server setup not only reduces the amount of maintenance required to keep everything humming but, as a direct impact, creates savings in operational and capital costs of approximately 50% when compared to non-virtualized systems.
4. In addition to the Server Virtualization discussed above, Desktop Virtualization is an additional means of improving service through quicker response and cutting costs, by providing virtualized desktop computers to branch offices, offshore outsourcing partners and mobile employees staying in touch on portable handheld devices such as tablets. These virtualized desktop systems provide a secure, consistent and scalable solution that not only saves IT dollars but also increases productivity.
5. Data Storage Virtualization allows for a fundamentally more efficient method for managing storage resources that improves both utilization and flexibility. Storage Virtualization can be used as a means of complementing and leveraging the current, existing data storage infrastructure.

It's All Good, With No Downside

Traditionally, when computer apps started running slowly or more memory seemed to be required, the answer was to add more hardware to the system. This not only increased capital expenditures but also inflated ongoing maintenance requirements with their associated costs, thereby wasting funds that could have been better utilized elsewhere.

By virtualizing your IT infrastructure, you make it simpler, more efficient, faster and with better performance and availability. Briefly said, it's easier to implement and manage a virtualized system.
