Artificial Intelligence: A Force for Good

-
  Artificial intelligence (AI) is a rapidly developing technology with the potential to revolutionize many aspects of our lives. While there are some concerns about the potential negative impacts of AI, there are also many ways that it can be used for good. Here are some examples of how AI is being used for good: Healthcare: AI is being used to develop new drugs and treatments, improve diagnosis and treatment of diseases, and provide personalized healthcare. For example, AI-powered systems are being used to analyze medical images and data to detect cancer and other diseases earlier and more accurately than ever before. Education: AI is being used to personalize learning, provide real-time feedback, and help students learn at their own pace. For example, AI-powered tutors can provide personalized feedback to students on their homework and help them identify areas where they need additional help. Environment: AI is being used to monitor and protect the environment. For ex...

The Five Ways to Migrate Applications to the Cloud.

-

 Hello, and welcome to my blog!

 This week we will be discussing the Five Ways to Migrate Applications to the Cloud. 

 Before we begin, perhaps it would be best to chat about what is Cloud computing. So, Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. 

 Now, to make things clear from some, the Cloud is a server that is located in another location. On that server, the user may store applications, which then he or she can have access to that information at a later time via the Internet. However, there can be some issues when trying to migrate applications to the Cloud, which we will be discussing. 

 Organizations seeking to move applications into the Cloud have five options: rehost on infrastructure-as-a-service (IaaS), refactor for platform-as-a-service (PaaS), revise for IaaS or PaaS, rebuild on PaaS, or replace with software-as-a-service (SaaS), according to Gartner, Inc.

 Let's dive in, shall we?

 Rehost redeploys an application without making any changes to its architecture, which can provide a fast cloud migration solution. There are pros and cons to this method as the primary advantage of IaaS is that the teams can migrate systems quickly without making changes to the architecture of the application; however, the primary disadvantage here can be the infrastructure's cloud characteristics such as the scalability can be lost.

 Refactor is another method where one can run an application on a cloud provider's infrastructure. The advantage of refactoring is blending familiarity with innovation, as "backward compatible" PaaS would allow developers to reuse languages, frameworks, and containers, leveraging code the companies consider strategic. The disadvantage here is missing capabilities, transitive risks, and framework lock-in. Though, the PaaS market is in its early stages, some of the skills that some developers depend on can be missing from the PaaS offerings. 

 Another method is modifying or extending the existing code base that supports the legacy modernization requirements. Using rehost or refactor options to deploy to the Cloud is called Revise. The revising option allows organizations to optimize the application to leverage the cloud characteristics of providers' infrastructure. The downside is that kicking off a (possibly significant) development project will require upfront expenses to mobilize a development team. Depending on the scale of the revision, Revise is the option likely to take the most time to deliver its capabilities.

 Rebuild is another method, which is what it says. Here you are discarding the code of the existing application and re-architect the application. Although rebuilding requires losing the familiarity of existing code and frameworks, the advantage of rebuilding an application is access to innovative features in the provider's platform. The primary disadvantage, so if the provider makes a pricing or technical change that the consumer cannot accept, breaches service level agreements (SLAs), or fails, the consumer is forced to switch, potentially abandoning some or all its application assets.

 And lastly, Replace, which is discarding the existing application or set of applications and using commercial software to deliver as a service. This option avoids the investment in mobilizing a development team when the requirements for a business function change suddenly. Disadvantages can include inconsistent data semantics, data access issues, and vendor lock-in.

 So, there you have it. The five ways to migrate applications to the Cloud by using the methods Replace, Rebuild, Revise, Refactor, and Rehost.

What Makes a Security Plan?

-
      Hello, and welcome back to my blog. This week, I would like to quickly discuss the levels that go into making a security plan. These types of plans are an important tool for IT departments and Cybersecurity Administrators to design a plan that will help protect or slow down an attack on the network.     Of course, security plans can vary from company to company; however, their purpose remains the same, with threats looming every day. With IT managers adjusting in response to the ever-changing threats, the created security plan must be designed to stop or slow down any attempt to breach network defenses. Below we will look at the principal components of a security plan and what they entail.    Separate Networks              As the name suggests, having more than one network can protect company assists from hackers and the like. The reason being is that having every computer on one network would lea...

Public vs. Private Clouds: A quick look at the Pros and Cons

-
Hello, and welcome back to my blog! This week we will be discussing the positive and negative sides of using public and private clouds.         For many small businesses, turning to the cloud would seem like a daunting and challenging task. Just thinking about the many different types of Cloud services and various companies that offer them would take time to sort out what you want and how to make the change.       I will cover the pros and cons of using public and private clouds in the hopes that you will come away with a little bit more knowledge on the matter than when you arrived. Of course, if you would like to know more about the different types of cloud services outside of these two, I am about to discuss, here is a link to one of my earlier postings here,  Link      So, let us go and dive into what these two types of cloud services are. If you have heard of companies like Google, Microsoft, and Amazon, you may also ...

The Differences between Hubs, Bridges, and Switches, and which one I would recommend using in your home or office

-
         There are many challenges that a network engineer will face when creating a network for a business. Even a homeowner may wish to design their network layout in the hopes that it will connect every room in their home. But what happens when you have multiple devices on a network and more than one device in a room? This can pose a problem if the tools available are not entirely understood by the one that is designing or implementing the network. This week, I will go into what a hub, a bridge, and a switch and their differences to help those looking for the differences and assist them in making the best choice for their home and business. What is a Hub?   Hubs provide a dedicated physical connection for each device that is connected to it. This can help reduce the possibility of one computer were to fail; it would not affect the other computers connected lose connectivity. The downside of a hub is that it shares bandwidth with other attached devi...
