Week 4 - Cloud Networking

Image
    Understanding networking is just as important when utilizing Cloud services. A good first step is having a good comprehension of the Open Systems Interconnect (OSI) model and the Transmission Control Protocol (TCP) model for troubleshooting purposes. Does the issue exist on the physical layer, for example the connection method between client and host has been damaged, or is the issue in software? Maybe there is a misconfiguration on one of the subnets. While in many situations the cloud service provider will do their own maintenance and troubleshooting, it helps to know the basic steps to verify the issue is not on the end of the client.     Its also vital to be aware of what the cloud provider will be responsible for, and what the client company will need to cover. Firewall rules, user credential management, and configuring multi-factor authentication for example may need to be covered by the client.  ~Amelia Weikel

Week 3 - Migration

Image
    While experimenting with the Cloud, some businesses may choose to migrate their operations partly or completely over to it. Before they take perform such a massive change to the company, they need to go overs pros and cons, and get answers to many questions.     What goals are planned by migrating (what's the point)? Which applications will work great in the Cloud? Which ones will operate poorly? How will data privacy be handled? How will the Cloud change the disaster recovery plan? How much time and money will be needed to train the employees on using the Cloud? How scalable would the business be if migrated to the Cloud? And so on.     Moving services to the Cloud will also allow users to work from home if need be, provided there is no data compliance protocol being breached by doing so. At the same time, that adds one more step information has to travel through before being stored on the servers, so that is a risk an organization will need to conside...

Week 2 - Virtualization

Image
      Before we can dive too deep into Cloud computing, we need to discuss virtualization. Virtualization is using one operating system to run another, for example using Windows 10, but running software that gives you a window of Windows 7, XP, or whatever the user needs at that time. While this can be done locally on one's own computer, virtualization takes up resources not every one can afford to give up. This is where Cloud virtualization takes place. Its the same concept, but rather than using one's own desktop to emulate a different operating system, the user borrows the hardware of a server in another room, town, or state which is generally significantly more powerful.     This is all handed with the use of a hypervisor. This can be thought of like a landlord dividing a building into multiple apartments. Maybe one client needs a two bedroom, while another client only needs one, saving space for someone who truly needs the space. ~ Amelia Weikel

Week 1 - Cloud Computing Fundamentals

Image
     Hello and welcome to my 11-week journey through the insights of Cloud computing! While I am not completely new to the topic, there is a lot I plan to learn and expand my knowledge on during this expedition. I'm Amelia, and I've been interested in everything computer since I was young when my dad built a Windows XP machine at the kitchen table while explaining the process to me. My grandfather has the most smart-home you'll ever see, especially for an older gentleman, so I suppose it runs in the family.     Fundamentally, Cloud computing refers to utilizing hardware not in the same physical location as the user. An example here would be someone using OneDrive or a similar program to save files. The advantage of using a Cloud service is one can access those files from any device with an internet connection, as opposed to being locked to their one personal desktop. ~ Amelia Weikel
