One of the biggest challenges the IT departments are facing today is to keep up their work environment. This is due to the need to maintain the IT infrastructure to be able to meet the current demand for services and applications, and also to ensure that in the critical situations of the company they are able to resume normal activities quickly. And here is where the big problem appears.
Many of the IT departments are working on their physical limit, logical and economical. Their budget is very small and grows on average of 1% a year, while managing the complexity grows at an exponential rate. IT has been viewed as a real cost center and not as an investment, as I have observed in most of the companies.
With this reality, IT professionals have to juggle to maintain a functional structure. For colleagues working in a similar reality, recommend special attention to the Virtualization topic.
Instead of speculating, Virtualization is not an expensive process compared to its benefits. Believing that depending on the scenario, Virtualization can be more expensive than many traditional designs. To give you an idea, today over 70% of the IT budget is spent just to keep the system environment functioning, while less than 30% of the budget is invested in innovation advantage, differentiation and competitiveness. This means that almost any IT investment is dedicated simply to “put out the fire” solve emergency problems and very little is spent on solving the problem.
I followed a very common reality in the daily lives of large companies, where the IT department is so overwhelming that you cannot measure the time to think again. In several of them, we have seen two completely different scenarios. A before and after Virtualization / Cloud. In the first case, what we have seen is a bottleneck with reality, drastic and resources to the limit. In the second scenario, a scene of tranquility, guaranteed safe management and scalability.
Therefore, consider the proposal of Virtualization and discover what you can do for your department and therefore, for your company.
Within this reasoning, we have two maxims. The first: “Rethinking IT” and the second is “Reinventing The Business“.
The big challenge for organizations is precisely this: Rethink. What to do to transform technical consultants?
Increase efficiency and security
To the extent that the structure increases, so does the complexity of managing the environment. It is common to see data center dedicated to a single application. This is because the best practices for each service request that has a dedicated server. Obviously the metric is still valid, because without doubt this is the best option to avoid conflicts between applications, performance, etc… Also, environments such as this are becoming increasingly detrimental as the processing capacity and memory are increasingly underutilized. On average, only 15% of the processing power is consumed by a server application, that is, over 80% of processing power and memory is actually no use.
Can you imagine the situation? We, first, have virtually unused servers, while others need more resources, and ever lighter applications, the use of hardware has been more powerful.
Another point that requires careful consideration is the safety of the environment. Imagine a database server with disk problem? What will be the difficulty of your company today? The time that your business needs to quote, purchase, receive, change and configure the environment to drop the item. During all this time, what was the problem?
Many companies are based in the cities / regions far from major centers and therefore may not think about this hypothesis.
With Virtualization it does not, because we left the traditional scenario where we have a lot of servers, each hosting its own operating system and applications, and we go for a more modern and efficient.
By working with this technology and we have underutilized servers for different applications / services that are assigned to the same physical hardware, sharing CPU resources, memory, disk and network. This makes the average usage of this equipment can reach 85%. Moreover, fewer physical servers’ means less spending on supplies, memories, processors, means less purchasing power and cooling, and therefore fewer people to manage the structure.
At this point you should ask, but what about security? If now I have multiple servers running simultaneously on a single physical server, am I at the mercy of this server? What if the equipment fails?
New thinking is not only the technology, but how to implement this technology in the best possible way. Today, VMware, the global leader in Virtualization and Cloud Computing, works with a technology cluster, enabling and ensuring high availability of their servers. Basically, if you have two or more servers that work together in the event of failure of any equipment, VMware identifies this fault and automatically restores all its services on another host. This is automatic, without IT staff intervention.
At runtime, the physical failure is simulated to test the high-availability and security of the environment in the future, the response time is fairly quick. On average, each server can be restarted with 10 seconds, 30 seconds or up to 2 minutes between each server. In some scenarios, it is possible that the operating environment will restart in about 5 minutes.
New services quickly become ready
In a virtualized environment, the availability of new services becomes a quick and easy task, since resources are managed by a Virtualization tool and not tied to a single physical machine. This way you can hire virtual server resources only and therefore avoids waste. On the other hand, if demand is rapidly increasing daily, it can increase the amount of memory allocated to this server. This same reasoning applies to the records and processing.
Remember that you are limited by the amount of hardware present in the cluster; you can only increase the memory to a virtual server if this report is available in its physical environment. This ends underutilized servers, as it begins to manage the environment intelligently and dynamically, ensuring greater stability.
Integrating resources through the cloud
Cloud computing is a reality; however, there is “No Cloud Without Virtualization”. Hosting providers now offer cloud tools through which you can create your own private cloud using the virtual structure all managed through a single tool.
After rethinking, now is the time to change, now is the time to reap the rewards of having an optimized IT organization, we have seen that when we do a structured project the high availability, security, growth capacity and technology everything become much easier, in the terms of benefits we can mention the following:
Respond quickly to expand the business
When working in a virtualized environment, you have to think in a professional manner to meet all your requirements, you can meet the demand for new services, this is possible with VMware Cloud Hosting because it offers a new server configured in a few clicks, in five minutes and offers a new server ready to use. Today, it has become crucial, since the start time for new projects are decreasing.
Increase focus on strategic activities
With the controlled environment, management becomes simple and it is easier to focus on the business. That’s because you get almost all the information and operational work is to have a thought of IT in business, and that is to transform a technical consultant. Therefore, a team will be fully focused on technology and strategic decisions, and not any other teams like firefighters, as they are dedicated to put out the fires caused.
Aligning the IT departments decision making
Virtualization allows IT staff to have the metric of reporting and analysis. Having these reports in their hands, with a professional tool they can lead to a fairly simple language and understand the reality of their environment. Often, this information supports a negotiation with management and, therefore, the approval of the budget for the purchase of new equipment.
Well friends, that’s all. You might find it lengthy, but it’s really hard to explain something important in fewer lines. Hope, the article will help you in planning your business well with Virtualization and Cloud Computing to reap maximum benefits.
If you are a business owner then you know very well that now online presence is very important for every business. In order to complete that requirement you will have to choose a proper website hosting provider for yourself that will match your requirements and also your budget.
You have to know about requirements in detail first as it will assist you to choose the suitable hosting plan for you. If you are a small business owner and want to make online presence then you can choose Shared Hosting plan. Shared hosting plan is the cheapest and hence also known as Cheap Hosting. In this plan you will be able to find prices for as low as $2.55 per month on the web. But in case of shared hosting You can’t customize this plan. If you have a big amount of visitors coming to your website every day then Shared Hosting can’t help you. In that case you have to choose something better than shared hosting which can manage more website traffic, give you a more customized environment and keep your server secured all the time.
Dedicated hosting is another hosting plan. It can fulfill your all requirements but it is costly than another hosting plan. There are many business owners who want to use dedicated hosting but don’t have that much budget. There is one option for those business owners, they can use VPS hosting. It is three times less expensive than a Dedicated Server. A Virtual Server works on the idea of virtualization. In this case a physical server is differentiated into many virtual servers with a virtual partition between them.
1. Virtual Server has its own RAM and disk space. You can customize it as per your requirements.
2. Users get their favorite operating system. You can reboot your virtual server when you want.
3. Your virtual Server can manage your website traffic independently.
4. Your hosting provider will be responsible ti maintain and update your virtual server in regular basis.
5. You do not have to worry about your backups. Your hosting provider would be responsible for that. But keep in mind before you choose any hosting provider that you have to ask them about backup schedule. Because hosting providers schedule their backup schedule on every day or weekly basis.
6. Now maximum hosting providers manage your virtual server free of cost. You do not have to appoint an employee to manage your server. In that way you can save money.
7. You can install and uninstall applications and also softwares of your choice. In this way we can say that you get better control over your server.
If you think about Virtual Server then there are so many advantages available with virtual server. But you have to verify some points before you select this hosting plan. You have to verify the amount of resources, quality of server management and also support quality which is provided by your hosting provider. You have to choose the suitable plan and hosting provider otherwise you do not get success in your business.
The word “virtualization” is similarly related with two biggest name Virtuzzo and Vmware, although so many differences about features and functionality are present in these two solutions. Now we discuss about their differences.
The level of virtual server creation is a main difference between Virtuozzo and VMware. In case of VMware, it create different virtual servers directly with hardware on the another side Virtuozzo create different virtual server at the operating system (OS) level. With virtuozzo solution every virtual server run on common physical hardware which have to use single common operating system. That’s why there is a limitation on overall functionality. On the another side VMware does not face these kind of issues, because it creates virtual server at hardware level. So, administrators can use their favorite operating systems. The great thing is that, VMware permits users to use different flavors of Windows and also Linux to operate in harmony on a common host.
As we previously discussed that, VMware creates virtual server with hardware level so, it can offer virtual memory to users. Virtual memory is a very useful thing, it permits users to utilize free disk space as temporary storage for whichever applications run out of physical memory or RAM. It also develops the stability and performance level of the system tremendously. On the other side Virtuozzo can provide single operating system to all virtual server and virtual memory is not present. If users have additional disk storage on their server then the whole disk work as a virtual memory.
Security and Reliability :
If all Virtual machine of a single physical server choose one common operating system to run then it would be a cause of weak security system and code faults. In this environment if any case any one operating system is hacked and the OS experiences a failure because of a bug in a software, then they all do. Also every new patch which you install on a Virtuozzo environment requires to be approved by the software provider. In case of VMware, it can utilize critical operating system patches.
At the end of this discussion we can conclude that VMware permits users virtual servers with a excellent uptime, simple portability and robustness on the other hand Virtuozzo is a OS level virtualization and it has it’s own limits.
