Operating system Expertise :
Os clustering:
Hardware clustering (sometimes called operating system clustering) is a hardware-based method of turning multiple servers into a cluster (a group of servers that acts like a single system).
In general, a hardware cluster is created by installing a number of blade servers on the machine that will control the cluster. Each of the blade servers functions independently of the others, although they all respond to the same requests. The operating system of the controlling server is responsible for monitoring the cluster and performing administrative tasks, such as deciding when failover is necessary and assigning the load of a failed node to a functioning server.
Hardware clustering typically requires some software application changes. The alternative to hardware clustering, application clustering, is a fully software-based method of clustering servers. Because application clustering doesn't require specialized hardware, it is usually less expensive to implement than hardware clustering.
High availabity:
In information technology, high availability refers to a system or component that is continuously operational for a desirably long length of time.
Since a computer system or a network consists of many parts in which all parts usually need to be present in order for the whole to be operational, much planning for high availability centers around backup and failover processing and data storage and access. For storage, a redundant array of independent disks (RAID) is one approach.Recent approach is the storage area network (SAN).
Some availability experts emphasize that, for any system to be highly available, the parts of a system should be well-designed and thoroughly tested before they are used. For example, a new application program that has not been thoroughly tested is likely to become a frequent point-of-breakdown in a production system.
Os/System Hardening:
Most computers offer network security features to limit outside access to the system. Software such as antivirus programs and spyware blockers prevent malicious software from running on the machine. Yet, even with these security measures in place, computers are often still vulnerable to outside access. System hardening, also called Operating System hardening, helps minimize these security vulnerabilities.
The purpose of system hardening is to eliminate as many security risks as possible. This is typically done by removing all non-essential software programs and utilities from the computer. While these programs may offer useful features to the user, if they provide "back-door" access to the system, they must be removed during system hardening.
Advanced system hardening may involve reformatting the hard disk and only installing the bare necessities that the computer needs to function. The CD drive is listed as the first boot device, which enables the computer to start from a CD or DVD if needed. File and print sharing are turned off if not absolutely necessary and TCP/IP is often the only protocol installed. The guest account is disabled, the administrator account is renamed, and secure passwords are created for all user logins. Auditing is enabled to monitor unauthorized access attempts.
While these steps are often part of operating system hardening, system administrators may choose to perform other tasks that boost system security. While Unix, Linux, Solairs & Macintosh and Windows operating systems can be hardened, system hardening is more often done on Windows machines, since they are more likely to have their security compromised.
Kernel optimizations:
In computing, the kernel is a computer program that manages input/output requests from software, and translates them into data processing instructions for the central processing unit and other electronic components of a computer. The kernel is a fundamental part of a modern computer's operating system.
When a computer program (in this context called a process) makes requests of the kernel, the request is called a system call. Various kernel designs differ in how they manage system calls and resources. For example, a monolithic kernel executes all the operating system instructions in the same address space in order to improve the performance of the system. A microkernel runs most of the operating system's background processes in user space to make the operating system more modular and, therefore, easier to maintain.
Database Management:
A database is an organized collection of data. The data are typically organized to model aspects of reality in a way that supports processes requiring information. For example, modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.
Database management systems (DBMSs) are computer software applications that interact with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases. Well-known DBMSs include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, SAP and IBM DB2. A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one DBMS. Database management systems are often classified according to the database model that they support; the most popular database systems since the 1980s have all supported the relational model as represented by the SQL language.
Database optimiaztions:
Database Administrators (DBAs) and developers are under increasing pressure to maintain the highest levels of database and application performance. They must balance customer satisfaction and productivity with rising costs and shrinking budgets. Throwing more hardware or resources at the problem is no longer an option. Neither are outages or delays. Optimization tools are needed to ensure that poor-performing code never reaches the production environment - where it is significantly more costly to correct bad SQL or application code.
Optimization Challenges:
At the Database Design
During Database Development and QA
Database Design:
Its starts at the database design layer. It is critical that the database designs conform to relational standards. Schema Examiner is a design or architecture validation tool that looks at the structure of the database to find improper indexing, normalization problems and other relational modeling errors that impact database performance. It not only finds problems, but recommends solutions, saving time and improving productivity during all phases of the database lifecycle.
Development and QA:
It is the developer's responsibility to prevent poor-performing SQL code from reaching production in the first place. DB Optimizer is a SQL profiling and validation tool that examines SQL queries to uncover inefficiencies and offers alternatives to improve SQL performance and prevent poor-performing SQL from ever reaching the production environment.
Optimiaztions at database level:
The most important factor in making a database application fast is its basic design:
Are the tables structured properly? In particular, do the columns have the right data types, and does each table have the appropriate columns for the type of work? For example, applications that perform frequent updates often have many tables with few columns, while applications that analyze large amounts of data often have few tables with many columns.
Are the right indexes in place to make queries efficient?
Are you using the appropriate storage engine for each table, and taking advantage of the strengths and features of each storage engine you use? In particular, the choice of a transactional storage engine such as InnoDB or a nontransactional one such as MyISAM can be very important for performance and scalability.
