Virtual services is the deployment of applications and services across a number of clouds in a managed manner. The cloud configuration determines the parameters of the VASAs. The cloud configuration will determine the characteristics of the IT environment such as service availability, scalability, reliability, and performance. To create a successful VASA, you will need to understand the benefits of cloud configuration and how it can help your enterprise.
Virtualization provides numerous benefits for your business. Virtual private servers provide port 80 and port 443 support. This allows you to access your applications from multiple remote locations even without installing any software or modifying any application settings. Virtual hosting also provides automatic logs integration. You can set up the logs on an in-house server or you can use centralized logging solution hosted through the internet.
One advantage of using virtual services is cost reduction. Virtual private servers do not require an expensive IP address and do not maintain huge amounts of server RAM. Virtualization reduces overall costs of hosting and this translates to increased profits for your business. The client traffic can be distributed across different sites without wasting any server resources.
Another benefit of using virtual services is its flexibility. You can easily create or modify your virtual services and you can easily reconfigure virtual environments on demand. If you are not sure whether you want to create virtual services or not, you can use the vanilla version and customize it later.
Your business can also experience greater agility when you use a virtual web host. You can experience simplified processes and reduced downtime if you switch to a new virtual service. Switching to a new virtual service may sometimes lead to unexpected results. If you switch to a basic or low level virtual environment, you may experience degradation in website performance that may lead to downtime.
Virtual SQL and memory accounts: Virtual SQL is used for storing sensitive data and memory resources on a virtual server. When you make changes to the website, these changes are automatically reflected in the SQL database. In non-virtual environments, you would need to recreate all the tables and create new rows in the database. Virtual SQL eliminates all these additional steps and lets you make updates directly. It also allows you to view all the information from any browser and at any point of time.
Database and its performance: A lot of your web visitors will visit the database pages and select the forms to fill in. They will fill in their details and when the forms are saved, these details will automatically be reflected in the database. The problem with most virtual service platforms is that it cannot guarantee a consistent performance of the database. With an application like Xenu, you can make sure that the performance of the database is always optimal.
Connection pooling and connections: You can connect more than one application to a single database server. But if you overload the connections to a single virtual host, the performance of that virtual host will be affected. The best way to avoid such issues is to allocate an individual port for each application and ensure that these ports are properly monitored to ensure that the overall resource usage is optimal. The virtual service may provide a best in class monitoring of these ports, and will automatically close the idle connections when the application gets busy.
Security policy: One of the important issues for any enterprise is security and this is also a big issue for virtual services. A security policy must be applied for every process to make sure that they perform in an efficient manner. If you have many ingress requests on the same port, the security policy will not allow the request to proceed further unless the security policy is enforced for every service. This can be easily ensured by creating an individual access control list for every service.
Encryption of the data stream: Most network administrators assume that when any application requests the information from the virtual host, it will be encrypted. This is not the case and hence the information obtained is not secure. To ensure security of the data stream, an IP address checker or SSL Certificate Authority is used to encrypt all the data transmitted. However, the main issue with this is that it creates another challenge for the clients to crack the password. It also creates a dependency on the virtual application that the IP address checker used cannot be applied to any other virtual service.
Traffic Shaping & Quality of Service: Virtual services are used widely and so there are many operators who use the datcripts for different purposes. Some of them may require high bandwidth to support their business needs while some may use it for better response time. For example a game developer may use the streaming datcripts for better game experience and so he may want to reduce latency. Traffic shaping & quality of service are necessary to provide smooth operation and thus need to be implemented in the virtual environment.
