 Hybrid Cloud and Multi-Cloud Networking

Objectives: Hybrid Cloud and Multi-Cloud Networking, The Different Between Virtual Private Network and Direct Connect.

1.      Hybrid Cloud and Multi-Cloud Networking

The purpose for this blog article is to discuss some helpful tips regarding hybrid cloud and multi-cloud networking, and the differences between VPN (Virtual Private Network) and Direct Connect – the important role both methods play in connecting network. A hybrid cloud is a network infrastructure that exists in two different places – on-prem and in the cloud. Like hybrid clouds is multi-cloud which is a network infrastructure that’s dedicated to two or many different platforms like, AWS (Amazon Web Service), GCP (Google Cloud Platform), or Microsoft Azure and Salesforce. With all these different platforms, one could wonder about the notable complexity in making these different network services and tools to communicate to and assist each other. The question then is, so why will any organization establish such metaphorical giant? The overall ideal answer to this “is that hybrid and multi-clouds are becoming more reasonable and popular due to their flexibility and potential cost benefits. A hybrid cloud is a typical transition phase as companies migrate to the cloud, and many companies ultimately decide to continue indefinitely with a hybrid infrastructure.”

2.      Different Between Virtual Private Network

VPN (Virtual Private Network) is a networking method used purposefully for establishing secured (encrypted) pathway (tunnel) for the safe travels of traffic over public Internet connection – meaning that there is a possibility for “latency” to become a problem based on “Internet weather conditions.” In some cases, SLA (Service Lever Agreement) might not cover Internet connection availability, however, the guarantee for high availability is possible with the creations and maintenance of several VPN connections. Alternatively, just as VPN tunnel can be creates to across public Internet, so as private Internet where an ISP (Internet Service Provider) will provide “MPLS (Multiprotocol Label Switching) connection,” that’s pricey.

To assist with cloud-based VPN network connection for users working remotely, a “VPN endpoint resource” must be configurated in VPC (Virtual Private Cloud). By configurating VPC, you will have the ability for sending “client configuration file” to remote users who want to install the VPN application on their machine (computer). One of several important aspects to understand is that VPN services will automatically scale as demand for use increases or decreases. In addition, charges apply “connection-hours.” If an organization were establishing a connection from its data center (headquarter) in Trenton, NJ, and to its VPC (Virtual Private Cloud) on Azure or AWS platform, for such connection to be a success, for example, the organization will “need a CGW (customer gateway)” device in their Trenton, NJ “network and a VGW (virtual gateway) service running on” their VPC as shown in the diagram below courtesy of CompTIA Cloud+ Guide to Cloud Computing.

3.      Direct Connect

Unlike VPN that’s inexpensive and provided relatively secure connection to network cloud resources, and low-speed connection, direct connect on the other hand is known for its high-speed connection, low-latency, a variety of characteristics and services base on providers, and far more security mode, but expensive. In the context of cloud networks, VPNs are often used to connect a single device to cloud resources or to connect a cloud network to an on-prem network over the public Internet. Whereas in context, a direct connection is far more balanced used devoted private infrastructure when connecting to an on-prem data center (network) through the infrastructure of a CSP (Cloud Service Provider). If you want to establish a direct connection from a data center to a public cloud, you can accomplish this simply by converting with a “CSP in a location called a col or colo (colocation).” In computer networking “colo is a data center facility” that’s dedicated to specifically to “interconnecting services providers, (both ISPs and CSPs) with their business partners and customers.” As a cloud user, you are allowed the option to ask for or demand direct connection within that specific facility (building) “to any number of service providers to support a hybrid or multi-cloud deployment” as long you can establish connection to the colo.

Listed below is a diagram of a colocation facility that establishes direct connections between service providers and their customers – courtesy of CompTIA Cloud+ Guide to Cloud Computing.

 Threats to Cloud Security.   Cloud computing is on the rise and becoming popular in the public and business enterprises sector. Many CSPs (Cloud Service Providers) like, Microsoft Azure, AWS (Amazon Web Service), and GCP (Google Cloud Platform) are offering their clients and users the opportunity to migrate the operations to the cloud by subscribing services () that fits their operation needs. There are many activities involved with migrating to the cloud that are important for the public and business enterprises to understand before making such leap (migrate). Speaking of migrating, the term security is one of the most critical aspects that concerns cybersecurity team members, and all proper measures must be taken seriously. The uprising of cyber threats to cloud computing increases by the day just as cloud computing becomes more and more popular. The following are lists of threats to cloud security: 1.       Data Breach - regardless o...

 Week One: Entry Blog. Hello to all, my name is Edward Cooper, and I was born and raised in Monrovia, Liberia, Africa. I came to the United States, November of 1996, and I reside in the beautiful state of New Jersey. I love working with different types of technologies and I just got through building a brand-new Personal Computer last month as I was pursuing my certification in Comp & Network Security Fund (CompTIA Security+), and Comp & Hardware and Software Mgmt. (CompTIA A+). I am currently taking a class in both Computer Server Environments (CompTIA Server+), and Network Mgmt. & Infrastructure (CompTIA Network+). Other than Windows Server that I have had some experiences (installed and configured) working with, I have not had experience with other vendors’ server platforms.   Speaking of server, I have some experience when it come to computer networking and I was able to build a home network (LAN) with four computers, Windows server, routers hubs, and a sw...

 Week Six: Internet Protocol version Six (IPv6). This week six topic focused on the fundamental concepts of Internet Protocol version six (IPv6), describing IPv6 practices, and the implementation of Pv6 in a Transmission Control Protocol/ Interprotocol (TCP/IP) network design. The Internet Protocol version four (IPv4) was developed for the purpose of assigning Internet Protocol addresses. IPv4 was developed to handled IP addresses for the foreseeable future, unfortunately, it turned out that wasn’t the case as the traffic (more computers became available in homes and smaller businesses) on the air wave begin too much to handle.  The IPv6 was developed as the replacement for IPv4. IPv6 comes with tremendous benefits that IPv4 didn’t had, and one of those benefits that IPv6 come with has to do with its pool of unlimitedly IP address. IPv4 is stay in used at this current moment as IPv6 translation begin slowly into replacing IPv4. There is no comparison whatsoever between IPv4 an...
