While cloud computing offers distinct benefits for virtually any enterprise with an IT department, concerns about cloud security have led many to seek for alternatives. To meet this need, private clouds have developed; these are similar to public clouds but are used solely by a single organisation, with all servers operating behind that organization’s firewall. Private clouds, however, can’t offer the flexibility and cost savings that make public clouds so attractive.
A hybrid cloud offers some of the benefits of both public and private clouds. In a hybrid cloud, the cloud infrastructure is made up of two or more separate clouds – private and public – that are discrete but linked together by either standardized or proprietary technology. This type of cloud infrastructure has some key benefits for web developers.
Security can be a serious concern for web developers, who often have to consider the possibility of unauthorized access to their site code or to data that is accessed via their sites. Hybrid cloud systems allow sensitive data and critical applications to be kept on the private element of the cloud, protecting them from vandalism or theft.
2. Lower Cost
Because some of the hosting of the site is taken care of by public cloud infrastructure, the overall cost to a company of running a website can be significantly reduced.
3. More Processing Power
Cloud-based hosting allows website developers to tackle more ambitious projects, as more processing power can be made available by running some applications on virtual machines.
4. Flexibility and Scalability
Hybrid cloud technology offers extra flexibility for developers. Less security-critical elements can be hosted on the public cloud side, allowing greater scalability as traffic changes.
5. Greater Site Stability
As well as spikes in site traffic, websites can face other challenges. For example, a site may need to serve information from a database or an application that has to respond to demands from elsewhere. In a hybrid cloud, load balancing between the private and public elements means that the website will not be adversely affected by such variations.
With the greater flexibility offered by public cloud elements and the security provided by the private cloud, a hybrid cloud can be an attractive arena for today’s web developers.
- Private cloud elements are firewalled for security.
- Public cloud elements allow for flexible Web hosting
- Load balancing allows for more ambitious site design.
