Q3:Project 2: Cloud Cost Analysis-In this project, due in Week 7, you will complete three tasks to outline the potential costs of the agency's Azure cloud pilot. • First, you will use the Azure pricing calculator to find the estimated costs associated with the pilot based on the agency's requirements and specifications You will then use these costs to estimate the costs for the agency to use Azure for one year, using either a pay-as-you-go model or a pay-for-one- year pricing model. . Finally, you will write a cost analysis memo to compare the two pricing options for the CIO. The memo will be two paragraphs long and will include a recommendation.See Answer

Part A ( 1300 words) ** 6 reference within 5 years google scholar) ** need intext reference Scenario: In your class, the teaching about Firewall and its working procedures. Now, assume that you have joined the industry as a network security expert after completing this unit. You need to expand your knowledge by upskilling and researching related content/materials from online and other relevant sources. TaskA.1:(Critical Analysis) ** please draft or draw a diagram to answer part of your answer In that role, your manager asked you to develop a plan for implementing and configuring "a virtual firewall for the public cloud". As a part of this plan, you need to write a report where you will explore the benefits of adopting virtual firewall for cloud computing, virtual firewall types, horizon scanning of this technology considering industry standard tools and present a case study describing the merits and/or weaknesses, other aspects (if you want to add any). TaskA.2: (Knowledge Reflection) In that role, you have also heard that your business is interested about implementing the emerging "zero trust (ZTA) security architecture (https://www.microsoft.com/en-au/security/business/zero- trust)". While you are giving a plan on virtual firewall implementation for your business, some people think that ZTA and Firewalls cannot work together whereas others think that they are complementary! How you will put your logic/argument and explanation from a security expert's point of view to provide "critical" insights with proper reasoning and logics and address this issue.

However, your manager wants you to cover why IDS for Smart Grid-IoT systems is different compared to typical network/nand possible solu Hints Part A1 Section 1 (Introduction) • Explain the importance of cloud security and the need for virtual firewalls • Briefly outline what the report will cover Section 2 (Benefits of Adopting Virtual Firewall for Cloud Computing) • Discuss the advantages of using virtual firewalls in a cloud computing environment • Highlight how virtual firewalls enhance security, scalability, and flexibility Section 3( Virtual Firewall Types) • Describe different types of virtual firewalls available for cloud environments Differentiate between host-based, network-based, and cloud-native virtual firewalls Section 4(Industry Standard Tools) • Discuss industry-standard tools and solutions for implementing virtual firewalls • Provide insights into emerging technologies and best practices Section 5 (Case Study) • Present a real-world case study of an organization that implementing virtual firewalls in their public cloud infrastructure • Discuss any additional aspects that were considered during the implementation Part A2 Section 1 (Introduction) • Provide an overview of the report's purpose and scope • Explain the relevance and importance of discussing the integration of ZTA and firewalls Section 2( Understanding Zero Trust(ZTA) Security Architecture) Define and explain the core principled and concepts of Zero Trust security Discuss the objectives and benefits of implementing ZTA in your context Section 3 (the role Firewalls in Security) • Describe the traditional role of firewalls in network security in your case • Highlight the strengths and limitations of firewalls in a dynamic threat environment relevant to your caseSee Answer
Q12:Description The purpose of this project is to develop a graph analysis program using Map-Reduce. This project must be done individually. No copying is permitted. Note: We will use a system for detecting software plagiarism, called Moss (http://theory.stanford.edu/-aiken/moss/), which is an automatic system for determining the similarity of programs. That is, your program will be compared with the programs of the other students in class as well as with the programs submitted in previous years. This program will find similarities even if you rename variables, move code, change code structure, etc.See Answer

So don't do it because you will get caught and you will get an F in the course (this is cheating). Don't look for code to use for your project on the web or from other students (current or past). Don't use ChatGPT or any other Al program to generate code. Just do your project alone using the help given in this project description and from your instructor and GTA only.See Answer

Q20: As the new cloud engineer, management knows you have fresh and new information. They want to begin implementing cluster technologies. This is the HW and SW they have tentatively started with: 20 HP Bladesystems 20 Dell PowerEdge Blade Servers WindowServer 2019 Red Hat Enterprise Linux (RHEL) HPE Intelligent Data Storage Platform Dell EMC Storage Arrays Base on your knowledge of clustering what recommendation or comments would you make(choose two) Mixing all the systems together and make a 40 system cluster you also state there is no problem mixing manufacture products. You recommend that they only use Dell products because they are superior to HP and do not use RHEL because is free and does not have the level of support of Microsoft You recommend two clusters one based on Dell and the other based on HP and you also suggest Windowserver2019 as the primary OS for one of those clusters and RHEL as the primary OS on the other. You suggest to management they not only have Fail Torrance with their initial systems but they will not have vendor lockout and you also suggest that with this cluster configuration they can support both Microsoft and Linux based Application and Solutions. Use HP as the primary cluster then use Dell as a HOT backup cluster, have both Sans attached to both systems for fast data storage. Window Server 2019 cannot clustering so only use Red Hat.See Answer
