Cloud Computing Migration Guide | Strategy

If you are an IT professional you can move different office services to cloud. The most common migrations are as follow.

Cloud Computing Basic migration:

  • Email
  • Data storage
  • Software as a Service

cloud computing migration strategy

Why email cloud computing migration:

 

  1. Cost: Suppose you have small company and have 25 to 30 employees and you want to setup exchange server for them. Now think for cost you need a server machine and licenses which cost you around $5000 and after installation and configuration for 24 hour up time you need labor that cost you 2500+ a month. And you need licenses for users running outlook on their systems.  On the hand you can get cloud email service with good feature and high disk storage per user at very low cost
  2. Ease of migration:  you can upload your already existing database on cloud web application very easily, sometimes you just need to upload a CSV files. Since you access you cloud email through web and by web interface you can manage your users email accounts very easily, you also manage their privileges with easy web interface. On the other hand for exchange server you need to train your network engineers which also increase your cost.
  3. Training: For cloud email service which have web base interface you don’t need hard training.
  4. Accessibility: The biggest advantage of cloud is that you can access it with internet from anywhere using a small application called web browser.

 

Why Migration of Data storage to cloud:

You can use cloud as data storage service as well, in this case cloud server provide you online storage of data where you can store data very easy, private cloud provides data storage in form of virtual disk like E:, P:, and S drive.

For data storage public cloud are out there like Amazon S3 and idisk. In data storage cloud there are cloud servers that you use for storage.

 

Software as a service:

Cloud computing also provides you application services, you can use different software online. Using software as a service in cloud computing has many advantages that are as follow:

Cost:

Software as a service is a low price service.  You don’t need to purchase the expensive software and licenses for different users. For example “Google docs” is providing you different online application like word, PowerPoint etc, which you can use online. Using Google docs you might not get the advance features which MS word or PowerPoint provides you but you can get functionality.

Applications are installed on cloud: In cloud computing applications are installed on cloud server you don’t need to install them on your system. This provide you more efficiency as you don’t need to required the hardware and software prerequisite for your systems, you just need to connect to you cloud and start using you application.

Enhanced collaboration:  Since your application is on cloud that way every one from company can access your application and can make modification to individual files and database which are available to other users as well.

 

How to migrate to cloud computing?

Migration to cloud computing is very simple and straight forward way.

Preparation and planning:

As a first step start planning, write down the services which you want to move on cloud. Cloud services provider selection is also part of planning.  In the implementation of the services will be a review of the current state of the platforms and perform the necessary tasks to prepare the environment for migration. Finally, the client will close with planning for migration work.

Migrating to the Cloud:

Within this phase and based on migration strategies defined and agreed with the customer, they will all work to migrate the information of current cloud platforms. The activities of this phase usually include:

  • Validation and acceptance by the customer
  • Running migration
  • Review of results

7 reasons to use Amazon S3 | Cloud computing online storage

What is amazon s3?

AmazonS3 storage is an online storage system and service provided by Amazon, theoretically, S3 is a global storage area networks (SAN), it showed a large hard drive, in which you can store and retrieve digital assets. However, technically, there are some differences in the architecture of Amazon.

Amazon S3 Storage

Amazon S3 structure:

Inside you find AWS S3 (Simple Storage Service) , a mass storage service, fully transparent, which allows us to hang all our data in the Data Center of Amazon without worrying about any limit.

You should know three key concepts of Amazon S3:

  • Amazon Buckets:

    are something like a directory or folder on your operating system, which will place our files. The names of the buckets are shared by the entire network of Amazon S3, so if we create a bucket, no one else can use that name for a new bucket.

  • Amazon Objects:

    are data entities in themselves, i.e. our files. An object stores both data and metadata necessary to S3, and can take from 1 byte to 5 gigabytes.

  • Amazon Keys:

    Keys are unique identifiers for each account and hosted file.Keysare a unique key within a bucket that identifies objects in each bucket. An object is identified uniquely within the whole bucket + S3 by its key.

Why Amazon S3 Storage?

If you want to have a scalable, high availability and inexpensive storage service, Amazon S3 is a good choice. Alone marketing cannot convince you, and then there are seven reasons to choose Amazon S3 as enterprise storage.

Only Pay for what that you use:

Since there is no monthly minimum nominal fee, you only need you to pay. For example, you are using more than 500TB of high-capacity storage space, so you pay less than $ .10 / GB / month. But whatever amount you have to pay 10 cents / GB / month is used to reduce the redundant storage, as well as data transmission costs. If you use has remained relatively stable, your actual costs may be very low.

Amazon also offers a free version of its services. If you are a small business demand for storage capacity, so each user can free registered 5GB of storage space. S3 provides 5GB of storage space to meet all your needs, and you spend the cost is very low. If you want to change the storage capacity required, you can easily transition to become paid subscribers of the S3.

Regional storage is available in Amazon S3

If your company has offices in different region of world, you can select your region for storing data, in order to increase the upload, download efficiency. Currently, Amazon five storage locations in the world, in order to better meet the demand. You can from the United States, U.S. West (Northern California), EU (Ireland), Asia Pacific (Singapore) and Asia Pacific (Tokyo) to choose.

It needs to be noted that if you choose this area of Northern California and Tokyo, you spend will be significantly increased. The cost differences may arise from the real estate prices and regional data center electricity costs and many other factors.

Unlimited storage of Amazon S3:

Amazon offersunlimited storageand S3 is design to provide99.99 % availability.Amazon remains the redundancy detection data for the entire data center. The purpose of the design of this system is to prevent data loss in a single data center in the event of a disaster or accident.

 Amazon S3 reliability:

Amazon’s service is reliable, safe and flexible. It supports a wide range of protocols and technologies work design.

 

Disaster Recovery with Amazon S3:

S3 provides a Disaster Recovery (DR)solution, the perfect combination of durability, scalability, availability and security. This is a good DR solution, it has unlimited storage, version control, and Amazon AWS Import / export functions.

Demand for DR and emergency backup to the Amazon processing, you need to compare to do so and to create your own DR site, the price difference between the maintenance and verification of backup hardware. The price of a few cents per gigabyte will allow you to give up the latter.

Amazon’s Virtual Private Cloud:

Amazon’s Virtual Private Cloud (VPC), you can build a complete infrastructure with a specific range of IP addresses, both public and private subnets, and your data stored in S3. This will be the one for you free to use the data center to achieve enterprise-class storage standard.

Amazon S3 is Secure:

Amazon S3 storage system is secure and safe. In amazon S3 these is concept of bucket, object and key, through with only authorize people have access to resources.

Why Network Virtualization | Benefits | How does virtualization

Why Network Virtualization

What is virtualization, how we can do the virtualization and willdescribe important reason for adopting Virtualization in this article. Today, virtualization technology can help businesses create a more efficient, higher manageability resource allocation more flexible data center.

What is virtualization?

Virtualization is away of creating of virtual version of some operating system and other devices like routers switches etc. In virtualization you can run multiple virtual machines, virtual routers on single hardware machine and can simulate any network design. There are some famous virtualization software which include:

–          VM Ware

–          Virtual Box

–          Hyper-V by Microsoft

–          Virtual PC

–          GNS3 for simulating cisco and juniper devices  (gns3 labs)

Benefits of virtualization:

Network Virtualization

The five most important reasons for adopting virtualization software:

1. ServerConsolidation and Infrastructure Optimization:

Virtualization allows for a significant resource utilization increased by pooling common infrastructure resources and overcoming the inherited model of “one application to one server”.

2. CostReduction of physical infrastructure with virtualization:

Since you can install multiple operation systems in single hardware machine using virtualization thus you can reduce the number of servers and hardware in your Data Center. This helps an enterprise to reducecost of requirements estate, power and cooling.

 

3. Flexible and improved operational responsiveness:

Virtualization provides a new way of managing IT infrastructure and helps IT managers to spend less time on repetitive tasks such as provisioning, configuration, monitoring and maintenance.

4. Major application availability and improved business continuity:

Eliminate planned downtime and recover quickly from unplanned outages.Also migration in virtual environments is also easy you can perform migration in virtual environmentwith no interruption in services.

5. Virtual environment is accessible:

You canmanage access and monitor protected desktop virtual environments from locally or remotely, with or without a network connection, from almost any desktop, laptop or tablet PC.

How does virtualization?

Basically, virtualization lets you transform hardware into software. Using virtualization software such as VMware or Virtual Box to transform or “virtualize” the hardware resources of an machine, including CPU, RAM, hard disk and network controller, to create a fully functional virtual machine that can run its own operating system and applications the same way as a computer “real”.

Multiple virtual machines share hardware resources without interfering with each other so that you can run simultaneously and securely multiple operating systems and applications on a single computer.

When you run VMware on some hardware it creates a software layer,that contains a virtual machine monitor or “hypervisor” that allocates hardware resources dynamically and transparently, to run multiple operating systems simultaneously on a single physical computer without even realizing it.

However, the virtualization of a single physical computer is just the beginning. VMware offers a robust virtualization platform that can be extended by hundreds of storage devices and interconnected physical computers to form an entire virtual infrastructure.
