Complex Configurations: Servers that are deployed in clusters to derive maximum availability and performance come under this classification. Hybrid of cloud instances and dedicated servers also come under this category. These robust and monstrous configurations are designed, built and managed to run custom made applications, large portal, rich media, resource intensive SaaS applications.

High Availability Config
High availability is defined as a website or web service that is aimed to be available with 100 % uptime. The emphasis will be on clustering, load balancing, distributing the clusters geographically. Before configuring such a system, it is essential to keep in mind on the following factors
1. Cost
2. Hardware / Software
3. Back Up
4. Geographical Distribution of servers
5. Type of content that is delivered
6. User Base
The following is one of the typical high availability configuration;
Firewall: Traffic from the internet is analysed and filtered via CISCO Pix firewall. The max sessions and thorough put of the firewall is designed based on the user base and scalability required in the future.
Load Balancers: This is primarily to distribute load among the nodes in the cluster. Web / Apps servers in particular.
Web/Apps Servers: This is a fully scalable cluster of web and apps servers. It is designed in such a way that a new node can be added to the cluster on the fly without any down time.
Gigabit Private Network: The Web / Apps server connects to the database server via private network. Connectivity with gigabit speed makes the access to database cluster as if it is on the same machine without any latency.
Database Clusters: No direct connection to the database server is allowed except from the application layer. Database clusters are high end monster servers with RAID 10 minimum configuration.
Backup: Fully scalable NAS / Storage Cloud.
Note : The above schema is a typical sample of a high availability configuration. Certain components can be added or removed based on the customer’s input.
High Performance Config
High performance is defined as a website or web service that is aimed to be accessed at higher speed and stability even when there is an abrupt spike in user access. The emphasis will be on high power clustering, load balancing, high throughput backbone connectivity. Before configuring such a system, it is essential to keep in mind on the following factors
1. Cost
2. Hardware / Software
3. Back Up
4. Geographical Distribution of servers
5. Type of content that is delivered
6. User Base

Hybrid Config
Hybrid configurations are a combination of multiple cloud instances and dedicated servers or clusters. When a site or an application is required to maintain backend database in a dedicated & restrictive environment due to regulatory compliances, hybrid configurations are used. While the application layer can make use of the robustness of cloud computing, the database layer can be kept in isolation in a dedicated environment. Before configuring such a system, it is essential to keep in mind on the following factors
1. Regulatory Compliance
2. Hardware / Software
3. Application Design and portability
4. User Base
Firewall: Traffic from the internet is analysed and filtered via CISCO Pix firewall. The max sessions and thorough put of the firewall is designed based on the user base and scalability required in the future.
Load Balancers: This is primarily to distribute load among the nodes in the cluster. Web / Apps servers in particular.
YBOX Cloud Instances: This is a fully elastic cloud which lets you deploy and scale computing instances on the fly. YBOX Cloud is developed over Citrix Xen Server and are based on a minimum of 2.0 GHz processor.
Gigabit Private Network: The Web / Apps server connects to the database server via private network. Connectivity with gigabit speed makes the access to database cluster as if it is on the same machine without any latency.
Database Clusters: No direct connection to the database server is allowed except from the application layer. Database clusters are high end monster servers with RAID 10 minimum configuration.
Backup: Fully scalable NAS / Storage Cloud.
