What are the pros and cons to install SSL Certificate in Shared Hosting?
Web Hosting has come along a long way with new methods of implementation and new techniques to utilize the resources efficiently among the group of users. One of the popular methods of webs hosting is shared web hosting. In this particular type of web hosting, different users have access to a common physical server and can utilize its resources with some limitations. These limitations can be related to several parameters such as email accounts, disk space, monthly traffic, database etc. These limitations may be taken as the downside of Shared Hosting but it offers the advantage of sharing of resources of the server. The sharing of performance resources allows for better utilization and availability of resources which increases the efficiency of the server. All the physical parameters of the server including CPU, RAM etc are available on the shared basis. It also improved the cost efficiency of the system as the expenditures of hosting are shared among the different machines and thus each user contributes to the cost.
Advantages of Implementing SSL
In spite of the disadvantages, SSL encryption comes with a lot of advantages which is clearly reflected as increased number of users are looking to implement HTTPS. Thus, it is bound to have pros that make SSL encryption increasingly popular. Let us now look at the pros of implementing SSL certificate VPS and Shared Hosting servers.
Protection from Malicious Third Parties
Implementation of SSL upgrades the security of the content that is being received over the network. When a VPS of a server based on Shared Hosting is protected by SSL certification, there is no way that malicious third parties can send any unwanted data. All the data is encrypted end to end and comes from a reliable domain. A user can send any sensitive data with trust with HTTPS encryption.
Data cannot be Intercepted by a Third Party
There are always some hackers and an intruder looking to steal vital information while it is being sent over a VPS. However, when the data packets are encrypted with SSL certificates, it is almost impossible for anyone to intercept information while it is being transferred between server and browser. Even if a hacker manages to hijack the connection, he will never be able to access any information as it is encrypted. Moreover, the connections are also encrypted and secured.
All those websites that are encrypted with SSL certificates always enjoy a higher rank in the results displayed by Google. Google always wants to provide access to trusted data and connections and thus it ranks SSL encrypted websites higher.
SSL certificates are symbol of Trust
A VPS which uses SSL encryption is looked upon with trust as the green padlock is seen as symbol of trust. A lot of users are also aware of the security that is offered by SSL certificates to the data packets as well as to the connection and thus it is easier for the user to trust.
The Disadvantages of Implementing SSL
Experts are divided in their opinions about the implementation of SSL in servers because it has its own pros and cons. Thus, it ultimately comes down to the end user to understand these pros and cons and take a decision on adopting SSL.
SSL Certification needs to purchase from a trusted authority and that will increase some cost of maintaining server. An individual may also create his own SSL certificate it will not be trusted by everyone. Thus, you need to purchase SSL Certificate from Certificate Authorities or its resellers.The cost of the certificate would increase depending on the domains and the sub-domains that will be covered by the certificate.
SSL Implementation can have a major problem if your server is trying to load content from websites that are not encrypted with SSL. It is sort of a compatibility issue that mostly arises with advertising and social media widgets. The problem is increasing getting less severe with time as more and more websites are getting encrypted with SSL certification. These warnings can easily put off a few users who do not understand much about certificates.
Issues with Proxy Caching
Virtual Private Servers or VPS that make use of SSL certificates consists of transfer of fully encrypted packets. Thus, there is always an issue with blocking of data at certain terminals that require data to be encrypted and decrypted. Thus, a server based on Shared Hosting would always require server to facilitate encryption before these packets are cached. It simply increases the complexity of the whole process. A shared web hosting server needs to take special care of such issues with SSL certification.
This type of issue is mainly a major concern for the large websites and would not affect small and medium sized websites too much. HTTPS implementation does come with a lot of advantages and thus it is up to the user to consider the severity of problem while looking to implement SSL certification.
Increased demand for Server Resources
Implementation of SSL increases the load on the server as it requires extra memory and processing cycles for accomplishing encryption. It is not always a problem as most of the servers have improved enormously over the last few years. However, when the resources are shared on a network as in case of Shared Hosting, it can cause a definite lag in the overall performance.
Unwanted delays in connection
While you are looking to encrypt a connection with SSL, you must be prepared for minor delays of latencies. SSL connections can cause a minor delay in connection because of the increased roundtrips as compared to normal connections. The delay in connection is minor and is not a big issue even with shared resources.
Some browser can have issues with Caching
It is another minor issue that is not experienced in most of the cases but it cannot be ignored completely. IE6 would certainly have issues with handling SSL encrypted connections. Modern websites with HTTPS connections may take longer time if the browser does not allow caching. Updated versions of the latest browsers should not have much problem.
