Cloud hosting – support for heavy traffic

Standard solutions, with many points of contact between offer and target customers, very often are connected with servers’ overload.

Cloud hosting – support for heavy traffic

Cloud hosting allows:

to handle hundred thousands visits

per month

unlimited, efficient development without building

systems of servers

eCommerce proprietary solutions

eCommerce proprietary solutions

We learnt from experience that in case of creating eCommerce systems, one of the biggest challenges is support for heavy traffic. Among applied proprietary solutions we introduced:

incremental backup;CDN server solution for static files.

••

Company’s security

This solutions provides data security. At i-systems we also invest in physical security of the cloud infrastructure. We use 24 h monitoring, our own energy security systems and extinguishing system for this purpose.

The advantage of cloud hosting is keeping each part of the system on separate data machines. Therefore, the infrastructure is not blocked.

Million visits

Cloud hosting is fully automated. Auto-scale process allows to increase resources of the servers in the event of detection of their absence. Thanks to this solution they can be doubled in a hour. Cloud hosting system is also fully scalable. This allows to create an infrastructure, which can be easily expanded, without large capital expenditures.

A quarter of million visits per month is a traffic which generates server’s overload. A popular solution in this case is dedicated hosting. However sometimes it can be not enough to solve all of the problems. The most efficient solution is to transfer hosting to the cloud computing.

What is cloud?

What is cloud?

Cloud computing is a kind of computing, where dynamically scalable resources are supplied via the Internet. User does not have to know how it works or deal with technical aspects. This is very important, especially in eCommerce, where trusted company deals with technical aspects of an online store while focusing on business development.

eCommerce cloud

The biggest problem is the amount of visitors to an online store at the same time.

eCommerce cloud

If traffic suddenly increases, and users start to open several subpages at the same time, we will have to deal with traffic generated by about 10 thousand people. This might be an overload for the part of the infrastructure.

Example

Cloud as a solution for “bottleneck” issue

Bottleneck is a place in server where something is blocked. It is a huge problem in eCommerce. Components of the online store, when placed on a single machine, begin to block each other. Web page load time is longer when one component waits for another. In case of cloud infrastructure the slowing part needs to have a new place on the server.

Dedicated server vs. cloud computing

We compared online store before and after cloud server implementation. A number of visits varies between 240 and 290 thousand per month.

Each server is responsible for only one task and therefore they do not block each other, even with relatively smaller computing power. It also means more than twice as fast page loading and complete stability.

Dedicated server

Servers are one of the most crucial parts of the eCommerce system.

Therefore, we decided to create our own, fully adjusted to the demands of e-market, cloud hosting infrastructure.

We present the nine technological advantages of i-systems solutions.

The advantages of i-systems cloud

i-systems cloud advantages

Dedicated servers or vps/cloud suppliers make clean servers available for their customers. The customer gets a password, IP address and other necessary information needed to administrate. Next, user has to configure, secure and optimize servers. At i-systems, all the works connected with server administration are conducted by a team to save time for this 3 processes.

1. Administration


One of the most important resources of eCommerce system is data. Keeping backups of all data, even after a few months, is connected with a necessity to have enormous disc resources. Therefore, i-systems team created a proprietary solution: incremental backup. It allows to recover data state, even a few months back, without a necessity to have all the disc resources.

2. Incremental backup


Vertical scalability of servers is increasing a number of processors and RAM in virtual server. This gives us a rapid possibility to increase the number of users the web can handle. However, this kind of scalability has a certain limit. At some point, the addition of resources is not possible or it is not effective anymore.

3. Vertical scalability


Horizontal scalability of servers is increasing an infrastructure by physically adding another servers and to split particular tasks between them. The task assigned to the particular server is not visible for the users in any way. This kind of scalability and tasks’ division allows multiple increase in number of users the web can handle.

4. Horizontal scalability


On every server, no matter who is the supplier, a range of functionalities is installed. In the context of hosting services it is very often that the only thing that is monitored is computer operation. What is excluded from the monitoring is the operation of each functionality separately. In case of i-systems cloud solution all the functionalities of the server are being monitored and its operation is checked every 5 minutes, 24/7.

5. Service monitoring


6. Service-level agreement

Thanks to the proprietary solutions we guarantee that all the server’s functionalities will work. Hosting suppliers ensures only the availability of the machine. When the functionality of www server stops working, which means that the webpage is not working, it is not a problem of the hosting company.


6. Service-level agreement

This can cause a situation, where hosting company fulfills the agreement (the hardware physically is working indeed), however it is not responsible for the failure of one single functionality. SLA for us is a responsibility for servers operation as well as the functionalities installed on them.


7. Adjustment to the system

Currently, the whole hardware infrastructure, network, as well as server software is optimized to fit i-systems software apps. Thanks to this, servers are free from panels which slow them down and they are created optimally to the eCommerce actions.


7. Adjustment to the system

Proprietary solutions and adjustment to the eCommerce, since the beginning makes the system work 40% faster than in commonly used Linux in the same hardware configuration.


Single Point of Failure (SPoF) is a threat to the servers. It is a part of the infrastructure, which failure is a cause of the whole system paralysis. This is why in i-system cloud solution every machine has among others:

8. Redundancy

two CPUs

two independent power supply units

disc matrix

double power source

Thanks to this, a failure of one element has no impact on servers and their services’ operation.

emergency power supply

links from multiple operators

double network devices


High Availability systems can be characterized by high reliability. Implementing HA system consist in connecting cloud hosting with system’s capabilities. Hardware working on i-systems cloud is based in two independent server rooms, 13 km away from each other. Such distance allows live replication of all data and automatic failure repair of even all data center.

9. High Availability
