our website moved to a new the 3rd hosting provider and now the performance and availability seems to be the best. Up till now we do not face any downtime reported by pingdom.com, although pingdom.com may have false alert sometimes.

our 1st hosting provider

- burst:

actually the hosting is quite good if your website is not too heavy load, but you have to restart/reload your web server and database server frequently because there is no swap for openvz. the price is affordable and reasonable, although there is some alert by pingdom.com, but with such cost and just 1-2 alerts per month is acceptable.

last year they started to provide XEN framework VPS but we did not try yet. i think the service would be similar. if you have limited budget, it is a good choice for start.

our 2nd hosting provider

- vps6:

the hosting provided XEN framework VPS and have swap support. however, the downtime alert is too much and finally we decide to switch to another hosting……

our current hosting provider

- linode:

no DOWNTIME alert from pingdom for 16 days!! it is a good news. In recent month, they have upgrade their bandwidth, then CPU, then now RAM. Although we did not yet upgrade our RAM, but i think we could upgrade it in near future. However, the only drawback is the cost if you have limited budget.

the migration is done and we got double RAM, cheer!

XEN v.s. OpenVZ

vps hosting – openVZ or XEN
this is the two main choices of vps hosting. which one do you need?

1. i need an independent environment
Your choice is XEN. XEN is similar to a dedicate server, other nodes on the same server will not affect you.
openVZ nodes would affect each other, however, the system resource usage is much less than XEN.

2. i am a linux starter
If you are not so familiar with linux environment, you can try openVZ first.
After you are confident, you can try XEN, based on price concern.

3. i need to see all logs
Your choice is XEN. we have try using openVZ, however, some logs are missing, for example auth.log, boot.log, dmesg, kern.log.
If you need to have a deep trace on the server, you can only choose XEN.

4. i need swap control
OpenVZ do not have swap. If you use up all the memory, your server would shutdown immediate.
However, for XEN, even if you use up the memory, you still have swap for buffer.

5. i need a better server performance
If OpenVZ is not oversell and have enough spare resource, the average performance of OpenVZ is much better than XEN.

web server selection

we are now moved to the new VPS server and really said goodbye to shared hosting. we tried a few unlimited shared hosting but all of them has some issues:
1) unlimited is not really unlimited, take care the terms and condition
2) website got redirect or rewrite easily
3) if the server you hosted got hacked, technical support cannot help
4) down time really cannot control (sometimes VPS too)

we moved to use VPS for around 1-2 years, it is really a good choice as compare to shared hosting because you can customize the server you want.
However, you have to take care the bandwidth and storage space usage very carefully.

so depend on your budget, in the internet world, you have these choices:
1) shared hosting
2) VPS hosting
3) semi-dedicated server hosting
4) dedicated server hosting
5) cloud hosting

we did not yet try cloud hosting due to its high cost…

if you have enough budget, you would choose cloud hosting or dedicated server hosting.
However, due to the budget concern, you have to select among the choice 1-3.

we are now using the VPS server from vps6 provider.
