For any business, be it a small, medium or large business, data is considered to be a valuable asset. Entrepreneurs are very keen in choosing a right system and infrastructure to manage their online applications but they fail to implement a system for data protection. A data loss equals a business loss. Hence, entrepreneurs should ensure data protection by adding RAID to the storage configuration.
Why Is RAID So Important?
Every business need to store an enormous amount of client data, confidential information and many more. If you are storing them in a multiple drive without utilizing RAID, there are chances of data loss due to a disk failure. You may defend telling, you have a regular backup. Still, there are chances of backup failure due to a sudden unpredicted failure the in hard drive. Implementing RAID is an indispensable option to ensure data protection and data accessibility without interruption.. RAID additionally serves as a performance booster too.
Things To Consider When Choosing A RAID Level
There a wide range of RAID levels with different functionalities. It is important to choose a right RAID level considering your business requirements. Choosing a wrong RAID level might land you in trouble. Let’s explore the criterias to be considered when choosing a RAID level.
Each RAID level incorporates different net usable space after accounting for RAID overhead. If capacity is your primary concern, you should be keen in choosing a right RAID level.
Each application on your system is unique and set for a different purpose. Hence, it is important to choose a RAID level that matches your workload.
Choose a suitable level that matches your system availability requirements, if your business is keen in ensuring less downtime.
A highly redundant array will be expensive whereas an average speed redundant array cost less. It is necessary to opt for an array that balances cost and performance.
You cannot opt for one-size-fits all approach when choosing RAID as one factor usually comes to the detriment of another. Some RAID levels can be utilized for performance but not for redundancy. Similarly, you can utilize some RAID levels for redundancy but not capacity and the functionalists differ in terms of cost too.
Let’s take a look on different RAID levels and how they cater your business requirements.
RAID 0 configuration offers maximum performance at low cost. As there is no RAID overhead all drives can be combined to a single logic disk. They also provide excellent capacity with 100% utilization. The main disadvantage of RAID 0 is that there is no data protection. A failure in a single drive results in a total data loss.
RAID 1 is commonly referred as disk mirror as it duplicates data in two seperate drives. Data is drive 1 is mirrored to drive 2. Since drive 2 maintains the clone of drive 1, capacity is utilized to 50% of the drives available. In short, RAID 1 ensures data protection, but no performance and capacity. RAID 1 is suitable if there are no capacity or performance requirements, but when the user requires 100% security for the data and this makes RAID 1 little expensive than RAID 0.
RAID 5 uses 3 or more drives in an array and also distributes parity data across all drives to improve reliability. RAID 5 outstands in the capacity as the parity drive always require one drive capacity less than the total number of drive in the configuration. It is possible to retrieve data from other drives if any one of the drives fails. However, it is not possible to recover the data, if there is a failure in both the drives. RAID 5 offers a great performance when reading data. On the other hand, low performance while writing as the system should be done with the writing of data block and parity data, right before the completion of an operation. Due to its high performance and reliability, it is expensive than RAID 0 and RAID 1.
As the name suggests, RAID 10 is a combination of RAID 0 and RAID 1 offering the benefits of RAID 0 in terms of performance and RAID 1 in terms of reliability. It is to be noted that RAID 10 is expensive as it needs a maximum of 4v drives and capacity utilization is 50% of the available drives. Overall it offers great performance and data protection with zero parity calculations.
RAID 60 is more or less similar to RAID 50 except it offers more redundancy. It is useful for very large capacity servers, especially for those do not require backup.
If you’re still confused to choose a suitable RAID level for your business here are a few simple tips. As RAID 0 offers no data protection and RAID 1 performs slower than RAID 5, 6, 10 they do not suit business needs. RAID 5 and RAID 6 are ideal for small to medium business where you can enjoy the increased performance and storage configurations at low cost. RAID 10 is a good option for a large business with a large budget and you can enjoy maximum benefits.
The scale of memcached DDoS attacks are becoming larger day by day, more frequent and complex. A Distributed Denial of Service (DDoS) attack is a cyber attack to make an online service blocked off by overwhelming a target website with fake traffic from numerous sources known as a botnet. It is an explicit attempt by attackers to prevent legitimate use of a service hosted on high-profile web servers such as payment gateways, banks, social media etc.
A DDoS attack can lead your business to an end make it to go offline in mere minutes causing a havoc to the business notoriety, expensive downtimes and income misfortune. It is hard to recognize the exact reason behind DDoS attacks because the systems that send false traffic are controlled by the sources cannot be identified. However, business runners can experience a piece of mind with a viable cure through DDoS Protected VPS.
DDoS Protected VPS
DDoS protected VPS comes with the DDoS mitigation deployment known as Anti DDoS VPS which are situated on a data center capable of high transmission that is hardened against DDoS attacks.
A good DDoS Protected VPS should be able to withstand the common types of DDOS attacks listed below.
- Fake traffic attacks
- Applications or server attacks
- Protocol-based attacks
As the quote tells “prevention is better than cure”, is it not a good idea to be aware of the real risk of suffering a DDoS attack, before you opt for ant anti-DDoS solution.
The attackers illegally gain access to your network and loot sensitive data. To deal with such attacks, server security audit and multiple backups of critical data are indispensable.
Threat to Customer Loyalty
In the competitive market, network and web service availability are basic for keeping up the the customer loyalty and to acquire new customers. DDoS attacks simply target the critical infrastructure causing a negative impact in the network performance which thus prompts to a loss of existing customer base and business development.
Cyber criminals threatens to block access to a particular service or website if a requested ransom is not paid.
One of the indispensable points for a business success lies in the reputation of the brand. When an organization fails to offer the services reliably, it is obvious that the customers lose their trust in your brand and this may degrade your notoriety in the business world.
In the online era, without a doubt, online business is a major source of revenue. If your web applications or services stopped responding amid the peak sales hour, a day or for a month, imagine the amount of revenue in the event that you went under an attack from a DDoS.
In short, A DDoS attack can lead your business to an end make it go offline in mere minutes causing a havoc to the business notoriety, expensive downtimes and income misfortune. It is hard to recognize the exact reason behind DDoS attacks because the systems that send false traffic are controlled by the sources cannot be identified. However, business runners can experience a piece of mind with a viable cure through DDoS Protected VPS.
DDos Attacks That Can Be Stopped With DDoS Protected VPS
DDoS protected VPS is the most reliable solution to eliminate DDoS attacks from disrupting your systems. Let’s look through the most prominent types of attacks which can be ended with a DDoS Protected VPS.
An HTTP flood attack is a kind of volumetric DDoS attack intended to overwhelm a targeted server with HTTP requests.
The attackers send a large number of UDP packets to the targeted server with the aim of overwhelming the device’s ability to process and respond.
A SYN flood attack is carried out by repeatedly sending initial connection request (SYN) packets to a targeted server machine, eventually the attacker will be able to overwhelm all available ports, causing the targeted device to respond to authorized traffic slowly or not at all.
Slowloris is a highly-targeted attack carried out by holding as many connections to the target web server open for as long as possible, where one web server is used to take down another server, irrespective of affecting the other services or ports on the target network.
In NTP amplification attacks, the attacker uses publicly accessible Network Time Protocol (NTP) servers to overwhelm a targeted server with UDP traffic.
Ping of Death
The attackers send multiple malformed or malicious pings to the computer in the “ping of death” attack.
As we know, DDoS attacks have become regrettably prevailing and they are frequently used for disrupting business eventually leading to revenue loss. Regardless of whether you have utilized different measures to alleviate the various effects of DDoS attacks, you will find that it remains tedious and exorbitant to truly deal with such attacks.
