Proven Steps to Migrate from UNIX to LINUX Environment

Linux server virtualization technology helps in mitigating business risk while ensuring a resilient platform for its subscribers. It goes without saying that today every business be it a corporate giant or startup is in a quest to cut back capital and operating expenses, leverage greater control, and gain maximum scalability for its core enterprise applications. Therefore, investing in a highly-manageable Linux infrastructure can help IT to respond to changing business requirements while improving productivity and reducing the total cost of ownership. On top of it, this versatile and high-performance setup delivers ongoing economic value for organizations of all sizes.

Recasting the virtual environment for your intensive workloads are the major aspects that every organization look forward to gain the momentum and cut down all the prequels linked with UNIX infrastructure.

Why enterprises are looking forward to Migrate?

There are numerous reasons why enterprises choose to migrate from bastion of UNIX infrastructure. Many chief executive leaders suggest the following reasons:

  • Maintenance and support of existing hardware and software cost too much
  • Lack of flexibility and agility
  • Less control over the deployed environment
  • Inability to respond to dynamic business needs

Ongoing technical advances in enterprise-class servers and solutions have made migration procedure entirely smooth and risk-free. To impart a greater control of LINUX technology over the conventional UNIX-based platform, it is imperative to know the proven steps that will assist you in successful migration process.

Initiate: Deploy a Test Lab or Pilot Project

In adopting Linux to power your intensive servers and applications loaded on them, enterprises typically choose one of the two key ways. Many organizations start the migration procedure with deploying a test lab, while a few companies initiate with Pilot project. The selection process between the two key approaches is industry-specific.

Deploy a Test Lab:

In this process, a small number of application frameworks are demonstrated and evaluated on LINUX platform as a standalone unit, separated from the entire application running in the production environments.

Pilot Project- Some companies choose a single lower-risk production environment to re-host in the form of pilot project.

Evaluate: Software compatibility

Before proceeding with the migration process, enterprises first need to check the compatibility of the existing software stack with Linux infrastructure. With up surging growth in IT ecosphere, there are a number of third-party software tools available for hardware enablement.  For example- Drivers are available for failover SAN connectivity, middleware, monitoring, storage enablement such as volume managers, utilities, databases and many more.

Once all the software meets the compatibility criteria, you can proceed with the migration procedure further.

Note: You are required to check Linux versions of your software in the first phase of migration. For this, conduct your own qualification tests without relying on IT vendor’s compatibility practices.

Execute:  Port your onsite server applications

Major organizations will have on-premise software that supports to power their mission-critical business applications. With good quality of source code, porting process will be smoothly performed. However, if the coding level is found quite unfamiliar, then you need to re-host UNIX software as per Linux compatibility so that it runs directly on Linux. Such approach could accelerate the process of migration for custom on-premise developed applications on traditional UNIX architecture.

Controlling: Train your IT professionals

In order to follow the success roadmap, it is inevitable that your IT staff should acquaint themselves with all the respective algorithms and strategies beforehand for effective commence of the migration process. It goes without saying that investment in knowledge is never a waste. Thus, your UNIX know how will certainly act as an upper hand in making Red Hat Enterprise Linux adoption swifter. However, there are some specific things still left to learn about x86 architecture. For the same, there are an impressive number of good tutorials and videos available on YouTube that can give your IT staff a better insight.

Ensuring Alignment with Business Standards

It is true that one size never fits all and the same can be translated for businesses functional across various sectors. Simply put, every business has specific system needs, and standards that support their apps. Some of the key pointers that IT professionals should bear in their mind– they should prepare a standard operating system framework that effectively falls in alignment with the business standards. There is a host of platforms that helps in codifying organizational needs in a decipherable and flexible manner.

Deployment of Pilot Project

Ostensibly, predicting about the timing and planning of the pilot deployment is quite an intricate process as it completely depends on the size and complexity of the different sites. However, abiding by some of the guidelines you can reap best out of your pilot project.

Closed-loop Approach Bestows Best Outcome 

Linux Server Hosting

Closed-loop approach gives a boost to decision-making by capturing the learning at every step. It ensures that all the deployed systems are working fine. On top of that, it gives quick insight into deployed systems.

Adopting RHEL platform can be a money-spinning journey for business leaders as it not only reduces upfront costs allied to hardware, software, and product licensing, but also supports faster time to market.  Linux servers hosting provide all the capabilities necessary for managing simple to complex application architecture with more granular control plus growth headroom when compared to RSIC systems. Aforementioned steps can help organizations to swiftly carry out the migration process.

Simple Ways to Secure Your Linux Servers

Linux servers are poised to considerably revitalize the way software applications are built, deployed, and instantiated. Designed to respond to the changing market demands including database management, proliferating web services and network system administration – these severs are high-potential variant of Linux open source operating system that includes CentOS,  Slackware, Debian, Ubuntu Server, and Gentoo.

Linux Server: A Buzzing & the Most Demanding Data Center Asset

Linux ServersBeing the most preferential operating system alternative over other pre-existing applications – Linux has protracted its range to a staggering level, transversely all industry verticals. Fundamentally, Linux loaded servers frequently setup a connection with clients operating on other operating system variants, such as Microsoft Windows. These servers are responsible for serving files created on and for such platforms.

 

Now, let’s take a sneak peek of the factors that makes Linux a demanding data center constituent:

Linux Servers

Questions must be cropping up in my reader’s mind that if it is so effective than how nefarious acts can intrude and affect its functionality. Right? To be precise, Linux servers are incontestably a perfect match to meet the demands of ‘bit turning to zettabyte’ business realm. Here is the catch, these servers function in an optimal way – provided if they are controlled, managed, and loaded with requisite security applications and monitored pertinently. Right from sharing files to Facebook or Wall Street serving real-time data to multiple concurrent end-users – Linux is the prime choice for everyone. Although Linux includes security mechanism like SELINUX, but sometimes even a small bug can give way to hackers, making it difficult for your business to sustain in the market.

Getting into Technicalities: A Driving Force behind Major Linux Adoption

Briefly, a Linux server can be isolated into several containers using hypervisors that provides a logical abstraction at the hardware level. Here each container runs in isolation and shares an operating system instance. Point that I want to emphasize on here is that a container can encapsulate any application dependency. Let’s say that, if a website runs on a specific version of the ASP.net, the Linux container can easily encapsulate that version, which in turn allow multiple versions of the same scripting language to be there in the same environment, and that too without bearing administrative overhead of a complete software stack, including the OS kernel.

Through this blog, I attempt to make my readers aware of some of the conquering tips and trials that can help them keep their servers at bay against annihilating factors:

Firewalls: Firewalls are one of the significant parts of any server configuration, helping businesses to protect their critical data and applications from unwarranted access. It restricts access depending on the categories, namely public, private, and internal services. In technical depth, it is a software application that restricts network traffic and access to insecure websites. There are a host of open source firewalls available for download such as Iptables, IPCop, Shorewall, UFW, Vuurmuur, pfSense, and so on. Also, Linux comes with built-in firewall that allows users to tune and configure the rules, based on the operational and organizational needs.

Linux Servers

Secured Passwords: Passwords are important to shield your critical data assets against forced access. Try implementing strong and unique passwords for each of your accounts. Remember, don’t use the same password for all; it’s a worst practice that can break your business wheels. A weak or common password can give access to your foes into your computer.

Tricks: You can use paraphrases, formulas, and spaces to make your password more strong and unforgettable. Also you can make use of password managers for the creating and remembering secure passwords.

SSH Keys

Secure Shell (SSH) is a network protocol that helps in establishing secure data transmission between two network devices. The encryption technology integrated in SSH protects confidential and integrity of information over non-reliable network, such as Internet. In this, public cryptography is used to substantiate the remote computer and thereafter enables that particular computer to authenticate the user. Encryption is the best technique to hem in your data into secured walls.

Virus Scanners: Viruses can shake your business’s bottom line by interfering or sometimes stealing your confidential data and sending across to wrong hands. Keep your servers 1000 miles away from infectious elements. Install a robust virus checker on your Linux server and keep on scanning it after few days or weeks. Also, keep your system updated with all the requisite security applications. On top of it, ClamAV is one of the best-in-class open source virus checking program that comes with Linux. It includes multi-layered scanner daemon and supports a host of file formats including signature languages.

Enable WPA on your router

Wireless connection is an indubitable aspect to access and transfer the content online. However, as long as the data is transmitted over the network, you have the probable chance of compromising to security. To add rigorous security in your wireless connection, it is imperative to enable encryption tools so that no one can open a nasty hole to your router. Among the standard security methods, some widely popular methods are WEP (Wired Equivalent Privacy), WPA (Wireless Protected Access), and WPA2. Using some encryption tools is always a secured choice than using none.  However, WEP is the least secure of these standards, implies that it can be easily compromised. That’s why it is better to enable WPA (Wireless Protected Access), which ensures safety in your local area network. On top of it, the second version named as WPA2 is the most secure encryption tool that scrambles the network connection, ensuring that no one keeps an eye on what you are accessing.

WPA key takeaways include:

WPA Authentication Process: Enterprise-level User Authentication via 802.1x/EAP and RADIUS

WPA eliminates most of the known WEP vulnerabilities, which is primarily envisioned for wireless infrastructure networks. This infrastructure involves stations, access points and authentication servers known as Remote Authentication Dial-In User Service servers (RADIUS servers). RADIUS server holds user credentials to authenticate wireless users before they gain access to the wireless network. WPA incorporates an integrated sequence of operations such as 802.1X/EAP authentication and sophisticated key management and encryption techniques to add security.

The Bottom Line: Today end-user demands from technology is plunging a step forward rampantly, demanding full-fledged IT solutions that include fastest deployment, patching, monitoring, and configuration in order to meet varying business and IT requirements. However, it is essential to ensure that what kind of service entitlements including security businesses wish their systems to have prior hemming in into the service bonds.

Smart Applications for Your Linux Server

Hosting providers across the globe employ enormous data centers powered by Linux servers. These hosting services are utilized by enterprises so that they can focus on vital business goals. In case you are planning to hire a Linux dedicated server hosting provider, the information present here will be useful. But before you read this blog, let me tell you that products and applications that run on Linux usually come free-of-cost.

Now, we will read about a few key tools which can revamp your Linux dedicated server’s routine. These tools are basically server side applications which boost the host’s performance to a great extent.

GRUB: It is a boot loader application that has been released under the GNU project. It enables your computer to use 2 operating systems on one machine. With its help, you can choose an OS of your choice during the first booting cycle. So the idea is that GRUB enables a multi-boot specification that suits your business needs.

In case GRUB is installed on your Linux dedicated server, you can pass boot time parameters directly to the kernel; you can also select numerous images of the kernel on a single OS.

Providers generally assist companies to install the GRUB boot loader atop their server.

TCP Wrapper: It is a free tool that is readily available on the internet. It is like a firewall for your Linux based server because every incoming packet is continuously monitored by the TCP Wrapper application.

Hacking attacks on a Linux sever are ducked by the TCP Wrapper. This tool checks all external sources to ensure that they are authorized to connect your Linux server. In case of an unauthorized attempt, login permission is denied on the application.

Zend Optimizer: It is a free runtime application which enables PHPs to run Zend Guard encoded scripts. Those who want to run encoded tools can download it for free.

It comprises of the Zend Encoder and the Zend Guard which encrypt specific files.
Zend optimizer supports PHP applications which decrypt and run apps on the fly. Hence you enjoy an enhanced runtime performance.

Now that you know all about 3 useful tools for a Linux dedicated server, make use of them through your hosting provider and maximize your limitations with an enhanced security model.
