December 22nd, 2016 Comments off

Hola!!  Scott Guthrie – Executive Vice President, Cloud and Enterprise Group, Microsoft recently announced in a blog post the availability of SQL server on Linux. The target for availability is mid-2017. This extension of SQL server on Linux will enable customers to have more flexibility in data solutions. A consistent data platform will be created across Linux, windows and on cloud as well.

With launching Microsoft SQL server driver for Linux, SQL server 2016 has been released with some fantastic capabilities

  • Revolutionary security encryption abilities enabling data to be encrypted in motion, at rest as well as in memory to provide concentrated security protection.
  • Every workload is supported by in-memory database increasing performance upto 30-100X.
  • Every employee will have Business Intelligence on every device including mobile phones of iOS, android and Windows.
  • New R support will deliver progressive analytics enabling customers to do real time logical analytics on analytic as well as operational data.
  • Some distinctive cloud computing capabilities will enable customers to deploy hybrid cloud architectures partitioning workloads of data across cloud based systems and on premises which will save costs and improve swiftness
  • With the #1, #2 and #3 TPC-H 10 Terabyte standards for non-clustered performance and the #1 SAP SD Two-Tier performance standards on windows will deliver unbelievable Data Warehousing performance.

The above mentioned improvements will enable building a complete platform for data management and much more.  With SQL server expanding to Linux, a broader set of users can be accessed and meeting them where they are situated. This will be a valuable asset to customers of Linux all around the globe.

What Is Proxy Server?

January 11th, 2013 Comments off

A ‘Proxy Server’ which is also called ‘Proxy’ most of the time, is a computer system which works as a gateway between a local network and comparatively larger network (most of the time internet). Security and improvement in performance are the two major factors making Proxy servers very popular. It also can be used to monitor incoming and outgoing resources throughout a specific network.

The main concept of proxy server working is existing in between connection of sender and receiver of data. The incoming data is received at one port and then it is forwarded to receiver / receivers (network) through another port. Due to it’s critical existence between sender and receiver a Proxy server makes it very difficult for hackers to access the data as there is no direct way to reach to network.

How it improves performance?
Proxy server has the ability to store the results produced for several requests made by number of various user of network. So when the repeated requests made by other users of that same network, for the same data (web-page), it need not to forward the request for the data it has stored in the memory. This saves a lot of time of responding the repeated requests sent by users.

How it improves security?
Proxy servers are also capable of of filtering requests. One can set proxy server to prevent the network users from accessing specific websites. So blocking malicious and unwanted websites by setting filter through a Proxy server is very efficient utility.

DDoS Attack Prevention System And Services

November 30th, 2012 Comments off

The popularity of DDoS prevention / mitigation services is increasing and the reason is that the method of this kind of attack’s execution is very well studied and well known to a lots of web hosting providers. DDoS stands for ‘Distributed Denial of Service’. DDoS attackers who are essentially also master crackers, only needs to create a network of compromise computers or aid of botnet which are are used collectively to attack on a web hosting server. DDoS attack is involved a high amount of artificial traffic flow. This high traffic flow caused in high consumption of bandwidth and packets on the web server to make it victim of DDoS attack. Not only high load of traffic but fake information requests also used on a large scale to bring down the web server, so that the genuine visitors and users will also loose the access of the same server.

DDoS Attack Prevention

DDoS Attack Prevention

There are many web hosting providers in India who provides effective DDoS Attack Protection services along with reliable web hosting services. These DDoS attack preventive services include use of various techniques to tackle hacking attacks which are also executed by using newer methods. The software and hardware used in such type of services are need to be updated on consistent basis as hackers and attackers keep studying all these things to overcome the security system.
All incoming traffic towards the web server is to be kept under inspection and a systematic analysis of all the traffic is need to be carried out to sort out the malicious traffic out of total traffic. As soon as any such malicious traffic is found which is generally from the same location is reported as threats detected through a specific alerts. Such alerts can save a web server before attack it done or before huge damage is done to the server after DDoS attack. Smart Web hosting companies also create a database of such attackers and hackers including the destination used for the attack, because this helps a lot to remain alert from such possibly dangers.

SAN(Storage Area Network) vs NAS (Network Attached Storage) vs DAS (Direct Attached Storage)

October 17th, 2012 Comments off

A NAS is cheaper storage than a SAN – Both can use RAID, if you had four 16 TB NAS boxes they would appear as 4 seperate pools of storage, conversely four 16 TB SAN’s would appear as one 64TB central pool of storage. Furthermore a SAN can be set-up to asynchronously replicate with another SAN over fiber perhaps in a different building, also a SAN can synchronously replicate with another SAN on a different site. Having an iSCSI interface on a SAN which therefore means the hypervisor is installed on the physical server yet it actual storage is on the SAN, meaning you can upgrade the entire physical server / blade without having to deal with moving large amounts of data about. Growth of the SAN is also easier, just by another SAN and add it to the pool. An example of how ESXi or Hyper-V can be used with a SAN (Two boxes), if you buy two servers with no hard drives at all, use a memory card installed inside the server to install the hypervisor (Install VMWare ESXi or Hyper-V) with one SAN (Two boxes that replicate with each other) per site, you can use the servers CPU and RAM to connect directly to the storage. The servers can then be separated into teir 1 and teir 2, etc allowing the virtual machines to use the CPU or RAM on a particular server. When VMware ESXi 4.1 Standard is used, you can use the vMotion to transfer servers whilst the users are using them.
DAS which stands for direct-attached storage is ideal for local data sharing requirements. It is the most basic type of storage and found very less when compared to SAN or NAS. In DAS storage devices are the part of host computer which are connected to a single servers with RAID arrays or tape libraries. Unlike SAN and NAS this enforces network workstations to access the server while connecting to the storage devices. Despite being oldest of the three DAS’s storage system still can be found among lot of IT infrastructures.

An Overview of R1Soft (CDP) – Ultimate Back-up solution

March 31st, 2012 Comments off

If you run a business oriented website then security is the area which needs to be specially taken care of. Backup is one of most important tasks on your website hosting account because it is the only hope for getting all your data back in disastrous situations like website got hacked, data is stolen away keeping your website totally empty, corruption in databases or data lost due to human errors. R1Soft is a backup solution for the organizations which want to backup daily change which happens in between the two backups performed. It is also well known as cheap and highly reliable disk to disk server backup application for both Windows Server and Linux server, this utility is known as CDP (Continuous Data Protection) in Web Hosting Services industry.

Conventional backup solutions are found with certain limitations especially when the data needs to be protected continuously. In these old type of backup solutions the total data of a server is needed to be backed up at each time you need to perform a backup. This causes the load on your server to rise and such large files become difficult to manage, you need more disk space for it. R1Soft came up with the backup solution which is capable of detecting files which have been changed since you performed your last backup, and it only takes the backup of such files. R1Soft overwrites such changed files only and saves not only disk space but also the other resources on your web hosting account. Furthermore for reducing the size of the data backed up compression technology is used efficiently which further makes improvement in speed while the backup and restoration process goes on.

According to the official website of ‘R1Soft’ near about over 200,000 mission critical Windows and Linux servers use R1Soft’s high performance disk to disk server backup software around the world.
