CageFS is one of the core features of CloudLinux. It is a virtualized, per-user file system that uniquely encapsulates each cPanel users, preventing users from seeing each other and viewing sensitive information. CageFS prevents a large number of attacks, including most privilege escalation and information disclosure attacks. It is design to add security to cPanel-based shared hosting environment.
With CageFS
Users only have access to safe files.
Users cannot see other users and have no way to detect the presence of other users or user names on the server.
Users cannot see server configuration files, like Apache config files.
Users have a limited view of their own processing file system, and cannot see other users’ processes.
CloudLinux was released to the market in 2010. Today, it is a must-have for any web host who cares about stability, security, and churn. It is used by more than 2,000 hosting companies on 20,000+ servers. CloudLinux is interchangeable with CentOS so any SysAdmin will feel right at home. Yet, it was specifically optimized for shared hosting. Web hosts that use CloudLinux report higher uptime, significant improvements in density (as much as 5x), 4x decrease in number of reboots, and 10x decrease in number of account suspension they have to perform. It has also produced a significant decrease in churn for a number of customers.
The software specifically made for web hosts running cPanel control panel with multiple accounts. If you are a shared host, or a design company that has to host sites on behalf of the client – CloudLinux is your friend.
CloudLinux + cPanel =
Improved stability by limiting the resources any single user can consume
In shared hosting, the most common reason for downtime is a single account slowing down other accounts on the server. Using cPanel & WHM software with CloudLinux utilizes innovative Lightweight Virtual Environment (LVE) technology, improving the density and stability of your shared hosting environment for all tenants.
Advanced server security
With unique CageFS technology, CloudLinux encapsulates each customer, preventing users from seeing each other and viewing sensitive information. It also prevents a large number of attacks, including most privilege escalation and information disclosure attacks.
Increased server efficiency
By monitoring and containing resource spikes, CloudLinux eliminates the need to leave server resources idle, providing you with the ability to host twice as many accounts on your cPanel & WHM server.
Multiple PHP versions
Using CloudLinux together with cPanel & WHM software gives your customers with the flexibility to choose the PHP version that they need.
Hardened kernel
The shared hosting environment is unlike any other and the CloudLinux kernel takes that into account. It can protect against symlink attacks and trace exploits, while restricting the visibility of ProcFS to only what is necessary — making your cPanel & WHM servers more secure.
From 2015 to 2016, Google has gradually rolled out the Mobilegeddon – a series of updates aimed to index and rank websites that are mobile-friendly. This update prompts most website owners to make sure their websites are responsive to the screen sizes of mobile devices.
With a few things going around the Google SERPs in the past weeks like FRED and other ranking changes, SEO experts have buried again in their desk figuring out what could be done to adapt to these algorithmic changes in the SERP. Until recently, Google confirmed that it is starting to roll out the mobile-first indexing in July.
Mobile-centric Culture
In the past years when the primary device to browse websites are the desktops and laptops, Google crawlers crawl and index websites based on their performance on the desktop. But as the lifestyle of being on-the-go become the new norm, people started to be mobile. The usage of mobile gadgets has increased drastically, especially in terms of personal searches. A year ago, Google announced that 60% of global searches were from mobile devices.
Other vital contributing factors are smartphone cost and internet connectivity. These two supports oxygen to heat up the usage of smartphones. With the continuous evolution of specifications, and rationalization of smartphone and data cost, people are more and more pushed towards mobile.
Mobile-first indexing
To support the increasing activity using mobile, Google has started to be a devout evangelist of better mobile experience. And other evidence of their commitment to this crusade is the release of mobile-first indexing on top of the mobilegeddon in 2015.
Mobile-first indexing is a little different and less disruptive than the mobilegeddon. It aims to prioritized indexing and ranking of websites based on their collective mobile presence. If mobilegeddon prioritized ranking based on mobile-responsiveness, mobile-first focuses on compliance and equivalence.
Should I get worried about my current ranking?
If you are worried about your current SEO, you might be asking yourself whether that worry is qualified or not, and here’s the answer:
YES and NO
YES – if you have a mobile version, but don’t deliver as a good as the desktop version
NO – If you are mobile-responsive and delivers valuable content, or with a mobile version that is equally the same with the desktop version.
Another issue that would cross your mind is, will affect my ranking and traffic?
Answer: There might be no great impact on the rankings, but there is in traffic. Remember the premise of having a mobile version which disconnects the user experience when one jumps from desktop to mobile? Well, that one can have a greater impact on traffic.
The bottom-line of mobile-first indexing is to make mobile searches better for all users, and that includes consistent user experience across devices.
