Servers have changed the way businesses operate and with the falling cost of parts, improved efficiency and the introduction of Cloud services – now is the perfect time to invest in your company’s future.
Servers Explained for SME’s
Servers are often dedicated meaning that they perform no other tasks besides their server tasks. Different servers do different jobs, from serving email and video to protecting internal networks and hosting websites.
What type of server am I looking for? What is the main purpose of the server? Should my server be on-site? Or will a cloud-based server be more economical and flexible? Answering questions like these will help you make an informed decision on your choice of server.
Mail servers move and store mail over corporate networks (via LANs & WANs) and across the Internet
Content & file sharing
Web-based email is portable
Access from anywhere any time
Scalable with growth of business
Internet connection needed to see your email
Provider may set limits on size of inbox or size of attachments
A proxy server sits between a client program (typically a Web browser and an external server (typically another server on the Web) to filter requests, improve performance, and share connections.
Isolate your private network
Restrict internet and private network traffic
Cache HTTP Requests
Can log all connections and activity
Intelligent filtering based on content
Reduced performance and speed
Not all services have proxied versions
Requires modification of client
Web Server serves static content to a Web browser by loading a file from a disk and serving it across the network to a user's Web browser. This entire exchange is mediated by the browser and server talking to each other using HTTP
Large data storage support
Bandwidth controlling to regulate network traffic
Provides web database access
Choose your operating system
Users do not require downloading plugins
Websites load faster
Users can configure the website to use content management system
Clients on the server can cause bottleneck of information
Administrators needed to control
Can be costly
A term often used synonymously with operating systems, a platform is the underlying hardware or software for a system and is thus the engine that drives the server.
Scalable with high performance
Secure and manageable
High capacity storage
Virtual Desktop infrastructure
Pay As You Go Model
Faster Time to Market
Speed & Flexibility
Rapid delivery of new capabilities
Large user base creates security issues
Dependent on one system
Sometimes referred to as a type of middleware, application servers occupy a large chunk of computing territory between database servers and the end user, and they often connect the two.
Provides a container model for applications
Provides Services for applications
Distribution of requests over multiple physical servers
Code & data integrity kept
More complex setup
Performance issues can arise if the network connection between your DBMS and Application Server if latency is high or bandwidth is too low for the amount of data being transferred
Real-Time Communication Server
Real-time communication servers, formerly known as chat servers or IRC Servers, and still sometimes referred to as Instant Messaging (IM) servers, enable large numbers users to exchange information near instantaneously.
Real Time - Instant & Fast
Connect to many people at once
Communicate with employees anywhere in the world
Relies solely on the internet
Expenditure on IT equipment
Technical issues may become a barrier to decision making
In 2009, the number of virtual servers deployed exceeded the number of physical servers. Today, server virtualisation has become near ubiquitous in the data centre.
Better space management
Drop in power improves efficiency
Faster server deployment
Standardised & easily replicated
Magnified physical failures
New management tools to monitor and configure
Complex root cause analysis
