Godaddy Acquired Sucuri

Godaddy, which is a leading company in domain registration and web hosting, announced the acquisition of Sucuri. Both Godaddy and Sucuri have published the announcements on their own blogs.

It’s really a good news for their customers. There are plenty of programs and web hosting companies, it’s only takes several minutes to set up a website. However, protecting our websites from cyber attacks is not easy even if we know basic knowledges and have done some security optimizations to our websites.

I can’t wait to see how will Godaddy integrate Sucuri’s services into existing products, and what benefits will this acquisition will bring to us.

Performance Benchmark of Vultr $2.5 plan

Vultr announced $2.5 per month plan about a week ago, and I was wondering how the performance is for such a low price. Here is a basic performance test of this VPS hosting plan, including hardware basic information, I/O test, network speed test and unixbench test.

The performance test was run on the following environment:

  • CPU: 1 core
  • Memory: 512MB
  • Storage: 20GB of SSD
  • OS: CentOS 6.8
  • Data center: Silicon Valley

Before showing test results, I would like to declare that the results may variable in different data center regions or on different server node. Even in the same server node, it may affected by other users, especially bad-neighbors and the test results variable from time to time.

Basic test

I was using a shell script from bench.sh, this test will show you the basic information of the VPS environment, I/O results and network speed results. From the screenshot below, I found the network connection  is a 1Gbps port at least, which was not disclosed on pricing page.

basic information about the VPS

CPU and Memory information

From the above test, we only see a brief information about CPU and memory, we can use linux command to get the detailed information about CPU and memory.

Here is a screenshot of running the command cat /proc/cpuinfo.

Unixbench

Unixbench is a popular server benchmarking tool. The results will depend not only on hardware, but on operating system, libraries, and even compiler. We don’t need to understand the complex algorithm inside the program, we just need to know whether the index scores is more than 1000. If it is, the performance is not bad. Vultr’s final index scores is 1337, and the performance is not bad.

Conclusion

According to the above test results, Vultr’s $2.5 plan is worth buying. The test results is better than I expected. Several hours later, I deployed another $5 plan instance, and the benchmark results are more or less the same even though the price is doubled.

Vultr add Firewall to Feature List

I am very glad that Vultr added Firewall service to the feature list, this is the most wanted feature second to backup service, which has been announced. Compared to system built-in firewall, there are some advantages:

  1. Reduce resource usage of instance, because package filtering takes place at a higher level on the network.
  2. Vultr firewall is managed through the Vultr control panel, it’s much more straightforward than Linux built-in firewall service which is configured in command line interface.
  3. Vultr firewall group can be applied to multiple instances, really a time-saver.

Vultr firewall is flexible and easy to use. First, create a firewall group. Second, add desired rules to firewall group. Third, apply a firewall group to a server.

Before you apply firewall to instances, you should know the differences between Vultr Firewall and Vultr DDOS protection service. Vultr Firewall is designed to enhance the security while DDOS protection is designed to block large volumes of traffic based on proprietary detection algorithms. Vultr Firewall may a little helpful in certain circumstances, because it can be used to block certain IP protocols or source IPs by rules.

It’s time to stop system built-in firewall and enjoy the convenience of Vultr web-based firewall service.

Vultr Upgraded All Plans and Announced $2.5 Instance

Vultr just upgraded all plans and announced a $2.5 per month plan, which comes with 1 CPU core, 512MB of memory, 20GB of SSD storage and 500GB of data transfer. Will you agree with me that Vultr is fighting back Linode which upgraded their plans two weeks ago.

This is a price list of upgraded plans:

How to upgrade for existing customers?

Please navigate to settings–>change plan and select the right plan, please note that downgrade is not supported. Here is a screenshot of how to upgrade plan.

Enjoy Vultr.

Cloudflare Parse Bug Caused Information Leaked

Cloudflare published a blog post of incident happened recently. If you are using, or used to be Cloudflare’s clients, you should pay attention to official announcements and change your administrator passwords and customer passwords if necessary. This bug was founded by Tavis Ormandy who is from Google Project Zero.

According to official blog, in some unusual circumstances, Cloudflare’s edge servers were running past the end of a buffer and returning memory that contained private information such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive data. And the most important is some of that data had been cached by search engines. Before the announcement, Cloudflare team has worked out with search engines to scrub the caches.

Cloudflare has not provided an official list of affected domains, here is an unofficial list of domains may have been affected. As i said, it is unofficial, and not all the domains in the list have been compromised, otherwise, the domains have been compromised may not in the list.

Let’s focus on the incident and stay tuned to official solution of solving this incident.

Linode Announced High-Memory Instances and $5 Linodes

On Valentine’s Day, Linode announced their first specialized instance family: High-Memory instances, and lowest priced instance: $5 linodes, along with a slight storage upgrade for $10 linodes.

Here is the details, first, let me show you what are High-Memory instances. High-memory instances are optimized for memory-intensive workloads like high-performance databases, in-memory caching, rendering and data processing. In other words, High-Memory instances come with more Memory, at least 16GB, which is $60 per month.

$5 is an amazing price, you will find several VPS providers have instances at $5 per month, such as Vultr and DigitalOcean. DigitalOcean’s $5 instance comes with 512MB of Memory and 20GB of SSD storage while Vultr’s $5 instance comes with 768MB of Memory and 15GB of SSD storage. Compared to them, Linode provides more resources, every $5 Linode instance comes with 1GB of Memory and 20GB of SSD storage.

Every Linode instance’s network out speed has been upgraded to 1000mbps at least, High-Memory instances even up to 10000mbps. Besides, $10 Linodes received extra 6GB of SSD, now they come with 30GB of SSD storage.

Linode upgrade their instances every year, the last upgrade was on their 13th birthday, June 16,2016.

If you are finding stable and powerful instances, Linode worth a try.

Hello, My Hosting Blog

This is the first post of this blog.

I’ve been thinking of start a blog talking about hosting for a long time. Now, here I am.

More than 10 years ago, I started to blogging and digging into servers, from Windows 2000 to 2003 to CentOS, and so on. In earlier times, we often bought shared hosting, that hundreds of customers share one server at the same time, which would cause bad-neighbor effects. But in nowadays, virtual private servers (VPS) are much more popular, with the help of development of information technology, VPS are getting cheaper and affordable, personal bloggers prefer powerful and flexible VPS than share hosting.

In this blog, I will share tutorials, hosting providers news, coupons and other aspects in related to hosting business with all of you.
