Most common concerns about using cloud infrastructure include:<\/p>\n
- \n
- Data security<\/li>\n
- Availability<\/li>\n<\/ul>\n
Data security is the most important question for those who consider moving their data to remote online storage. Everyone needs to be sure that unauthorized users will not have access to valuable data; that is why all major cloud vendors are keen to fulfill the security-related demands of their customers.<\/p>\n
Another typical question is: what if the Internet connection goes down? Nowadays, a corporate customer should have high-speed access to the Web with a reserve channel to handle any type of forced offline time. Modern cloud vendors, on the other hand, guaranteed uptime and responsiveness of their solutions through special SLAs.<\/p>\n

<\/p>\nThe main benefits of cloud migration are:<\/p>\n
- \n
- Scalability<\/li>\n
- Increased durability (disaster resistance)<\/li>\n
- Simplicity<\/li>\n
- Lower pricing<\/li>\n<\/ul>\n
With cloud infrastructure, you can acquire several more VMs or cancel excessive ones whenever you need without tracking available hardware resources. All major cloud vendors keep copies of your data in several physical locations, thus significantly reducing the risk of data loss in case of a disaster.<\/p>\n
You also do not have to care about hardware, cabling systems or power supplies. This means there will be fewer problems when creating a logical structure of any complexity. Finally, with cloud infrastructure, you pay only for what you use. Each cloud vendor in most cases offers the option to cancel the additional storage or computing resources usage and cut the costs instantly.<\/p>\n
Who Rules the Cloud Industry<\/h2>\n
There are several big cloud vendors in this market worldwide. We will take a closer look at three of them which are the most popular: Amazon<\/strong>, Google,<\/strong>\u00a0and Microsoft<\/strong>. These companies have built formidable rosters of cloud solutions matching the needs of any customers. Each of them owns a huge network of data storage and computing facilities all over the world which increases the safety and flexibility of the customer's infrastructure in the vendor's cloud.

All cloud platforms support basic infrastructure options like VPN tunneling, VM auto-scaling and isolating. It is often convenient to use online storage systems or VMs from different vendors. However, it is necessary to ensure that selected services will work properly with each other. For example, connectivity between two instances in Azure and AWS will likely be worse than if both instances were located in the same cloud.<\/p>\n
What tools to Use<\/h2>\n
Most server applications today have their native data export tools for moving documents and databases to the cloud, as well as creating a virtual infrastructure. However, there is a more unified way to do such things \u2014 image-based backup and recovery.<\/p>\n
