What Is a Hybrid Cloud?

A hybrid cloud is an infrastructure that you can use to bridge cloud and on-premises environments. It requires that your environments be integrated. Hybrid clouds can be composed of either public or private clouds and can be combined with a multi-cloud strategy. 

 

Public clouds are remote clouds that are hosted by third-party vendors. For example, Google, Microsoft, or Amazon. In a public cloud, you share servers and networking with other tenants. Private clouds are remote (often co-located)  or on-premises clouds that are managed by you or a third-party vendor. 

 

In private clouds, you use servers and network connections that are dedicated to your use only. A multi-cloud strategy is one that combines cloud services from multiple vendors.

To be considered a hybrid cloud, an environment must:

 

Network multiple servers or devices across multiple cloud environment types

Offer increased data availability and scalability 

Enable the flow of workloads and data across separate cloud environments

Hybrid Cloud Benefits

There are numerous benefits to hybrid cloud environments, including the following:

 

Improved business continuity—enables you to store backups and recovery resources in the cloud while retaining original copies on-premises. You can use hybrid environments as a failover in case of disaster or local outage. 

Scalability—cloud resources enable you to scale as needed and on-the-fly. You can more quickly provision resources than is possible with on-premises hardware and you only pay for cloud resources while in use. Additionally, hybrid resources can enable you to extend the life of on-premises resources, reducing technical debt. 

Increased availability—enables you to distribute traffic and applications across your environments for greater availability. Distributing processing power and requests prevents bottlenecks and reduces the risk of single points of failure.

Supports DevOps—enables DevOps teams to quickly provision resources and deploy projects. Organizations can retain sensitive data and operations on-premises without limiting the speed and flexibility of development operations.


IP addresses on your network with Linux

How many times have you tried to configure a static IP address for a machine on your network, only to realize you had no idea what addresses were already taken? If you happen to work with a desktop machine, you could always install a tool like Wireshark to find out what addresses were in use. But what if you"re on a GUI-less server? You certainly won"t rely on a graphical-based tool for scanning IP addresses. Fortunately, there are some very simple-to-use command line tools that can handle this task.

I"m going to show you how to scan your Local Area Network (LAN) for IP addresses in use with two different tools (one of which will be installed on your server by default). I"ll demonstrate on Ubuntu Server 18.04.

The professional works in close coordination with the developers to support new features, software releases, and other technical issues. They should provide quick and instant solutions for issues related to the production Linux systems. The Linux System Administrator works to optimize real-time performance requirements and system backups.


Number of cybersecurity volunteer groups growing

The CTI League is not alone in rounding up cybersecurity volunteers to help organizations, particularly healthcare organizations, during the coronavirus crisis. Another group called the COVID-19 Cyber Threat Coalition consists of several thousand volunteer security experts who are tracking online cybercriminal activity, particular the rise in new health-related domains that appear ripe for malicious activity.

 

Weiss says his team plans to work this group and other ad hoc emerging volunteer groups in much the same way his ISAC is working with the CTI League, namely by grabbing the indicators they have and sharing them with the group’s members.

Yet another group, Cyber Volunteers 19, was set up in the UK by Lisa Forte, founder of RedGoatCyber, along with cybersecurity practitioners Daniel Card and Radoslaw Gnat. CV19 says its primary purpose is to facilitate and enable a volunteer matchmaking that gives healthcare services access to a pool of cybersecurity experts.

 

As the number of volunteer efforts grow to help tackle COVID-19 threats and scams, it’s clear the current crisis has brought many members of the industry together with a sense of common purpose. “We’ve never seen this level of collaboration across the board for all aspects of the problems that are cropping up due to the pandemic,” Rogers said.


Network Topology

The LAN networks is set up in the system of peer to peer method while in WAN, an admin server or client-server is established from where the data traffic is maintained.

 

The function of a LAN connection is like the electrical connection or electrical wiring of our house. It is restricted within the borders of our house while in WAN connection the is more like the electrical wiring of the public electricity facility of our locality, it is not restricted within the borders of our house and could have a long range of distance.

 

In LAN connection the connection is peer to peer connection meaning the transferring of data occurs between two devices or computers in which one computer acts as a server for another.

While in WAN a powerful computer is centralized which can be classified as the server that acts as a hub to less powerful personal computers or workstations (called clients) that are connected to the server. The Internet is the best example for WAN while LAN can be considered as the connection or network within an office or organization or institute.

 

So, now you might be curious about what is the main use of WAN and LAN? The answer to this question is quite simple, the establishment of communication and transferring of computer data between the users. Now, you might be thinking about what?

But they are used to derive different terms? Are they similar in function? The answer is yes, even though they seem different terms, but they have similar functions which are to establish means of communication and transferring of data between users from one device (or computer) to another regardless of the distance.

 

This might clarify some question which might appear to you, however, if not you might want to see some of the commonly asked questions below and find your answer.


How important is CompTIA Certification?

The need to advance or improve one’s credentials has become an import factor in this growing world. To beat the competition one should do the certifications and be a step ahead from others. There are many certifications, based on the expertise you have in, you can choose the one most relevant. Out of many one is CompTIA, doing which you not only gets the recognition but also the growth you would want. CompTIA is one of the most valued certifications as it covers a variety of fields like computer networking, IT security, Linux programming etc.

 

One way to be ahead of others, in a growing world of competitive job market the need to advance or improve one’s credentials cannot be ignored. For the beginners of the IT field CompTIA A+ is the most recommended of all as it makes you perfect as a computer technician. Topics covered under A+ are as installation, preventative maintenance, networking, security and troubleshooting. The exam is internationally accepted and relevant, also it is vendor neutral. Many employers see it as the proof of your ability to work with computers. No wonder, experts call A+ certification as a step in the right direction to more advanced CompTIA certification.

Once you are done with CompTIA A+ certification, you would look out for the next level i.e. CompTIA Network+ which is even more important than the CompTIA A+ certification. This certification makes you efficient in running, maintaining, troubleshooting, installing, and configuring computer network infrastructures. Companies which have large number of computer networks, connecting many employees, this certification is for them. There is high demand for IT networking professionals, so getting your CompTIA Network+ certification is a good next step after you complete your A+ certification.
