e-Business Solutions
Large business sites are models of dynamic change: They usually start small and grow exponentially with demand. They grow both in the number of unique users supported, which can grow extremely quickly, and in the complexity and integration of user services offered. Successful business sites manage this growth and change by incrementally growing the number of servers that provide logical services to their clients either by the servers offering multiple instances of themselves (clones) or by partitioning the workload among themselves and by creating services that integrate with existing computer systems. This growth is built on a solid architecture foundation that supports high availability, a secure infrastructure, and a management infrastructure.

Cierra e-Business Solutions operate on an architecture that strives to allow clients to meet four goals:

Linear scalability -- continuous growth to meet user demand and business complexity.
Continuous service availability -- using redundancy and functional specialization to contain faults.
Security of data and infrastructure -- protecting data and infrastructure from malicious attacks or      theft.
Ease and completeness of management -- ensuring that operations can match growth.

Scalability

To scale, Cierra Business Solutions splits a Web site’s architecture into two parts: front-end (client accessible) systems and back-end systems where long-term persistent data are stored or where business-processing systems are located. A stateful or content-sensitive load-balancing system routes requests to the correct back-end systems. Business logic complexity is increased in a manageable way through functional specialization. Specific servers are dedicated to task-specific services, including integration with legacy or offline systems. Cloning and partitioning, along with functionally specialized services, enable these systems to have an exceptional degree of scalability by growing each service independently.

Availability

Cierra Business Solutions makes front-end systems highly available as well as scalable through using multiple, cloned servers, all offering a single address to their clients. Cierra Business Solutions uses load balancing to distribute load across clones that are no longer offering a service but can be automatically removed from the load-balance set while the remaining clones continue to offer the service. Back-end systems are more challenging to make highly available, primarily due to the data or state they maintain. Availability is also largely dependent on enterprise-level IT discipline, including change controls, rigorous test and quick upgrade and fallback mechanisms.

Security

Security -- managing risks by providing adequate protections for the confidentiality, privacy, integrity, and availability of information -- is essential to any business site success. Cierra Business Solutions uses multiple security domains, where systems with different security needs are placed and each domain is protected by a network filter or firewall.

Management

Management and Operations broadly refers to the infrastructure, tools, and staff of administrators and technicians needed to maintain the health of a business site and its services. Because many sites are located in what is often called a hosted environment, Cierra Business Solutions provides management and monitoring with the ability for remote administration.
