Incca 610 Cloud Services And Technology You Assumed The Role Of An I

In CCA 610: Cloud Services and Technology, you assumed the role of an IT analyst at BallotOnline, a company providing electronic voting solutions worldwide. Your proposal to begin migrating systems to the cloud has been approved. BallotOnline has now initiated preparations for the cloud deployment. The company decided to start with deeper investigations of crucial technologies enabling cloud computing. You became acquainted with the basics of these technologies in CCA 610. In this project, you will conduct more in-depth investigation of cloud networking, which makes cloud connectivity on-demand operations possible.

You need to have a good understanding of this as you prepare the BallotOnline network for migration to the cloud as well as designing the appropriate network infrastructure in the cloud for BallotOnline. To do that, you will assume the role of a BallotOnline network engineer. You will explore the network protocols that enable the company and its customers to connect to the cloud, as well as technologies making it possible to create on-demand in-cloud virtual networks into which the cloud resources will be deployed. You will conduct two lab experiments exploring the TCP/IP protocols and software-defined networking. You will also perform a subnetting task to demonstrate your understanding of TCP/IP network addressing.

Introduction

With the increasing adoption of cloud computing, understanding cloud networking technologies is crucial for organizations like BallotOnline planning to migrate their infrastructure to the cloud. This report provides a comprehensive exploration of key networking concepts, protocols, and technologies that enable cloud connectivity and management. The focus is on TCP/IP protocols, DNS, subnetting, and software-defined networking, which are fundamental for establishing secure, scalable, and efficient cloud environments.

Networking Concepts and Basic Protocols

Fundamental networking concepts such as Local Area Network (LAN), Ethernet, and packet switching form the backbone of cloud computing infrastructure. Packet switching, the process of breaking data into smaller packets for independent transmission, ensures efficient and reliable data transfer across networks (Tanenbaum & Wetherall, 2011). Understanding these concepts is essential for designing cloud networks that are both robust and flexible.

The layered model of network protocols, especially the TCP/IP suite, facilitates interoperability and standardization (Comer, 2018). TCP/IP comprises several layers, including the Internet Layer (IP) and Transport Layer (TCP), which work together to ensure data communication integrity (Kurose & Ross, 2020). Application-layer protocols such as HTTP and SMTP extend this suite to provide services over the internet.

Internet Packet Switching and IP Protocol

The Internet Protocol (IP) is central to connectivity in cloud environments, employing packet switching to transmit data as small, independently routed packets. This approach supports scalable and efficient communication over global networks (Deering & Hinden, 1990). IP addresses identify devices on a network, and IPv4 remains predominant despite the transition to IPv6 due to existing infrastructure constraints (Hinden & Deering, 2017).

BallotOnline requires IPv4 addressing to create virtual networks and assign addresses to cloud resources. IP addressing can be assigned statically or dynamically through DHCP servers. DNS complements IP by translating human-readable domain names into IP addresses, simplifying network management and user access (Mockapetris, 1987). IP routing, performed by network routers, facilitates the transfer of packets across networks by learning and updating routes dynamically (Limoncelli et al., 2014).

Transport Layer Protocols: TCP

The Transmission Control Protocol (TCP) is responsible for ensuring reliable data delivery in cloud communications. It establishes connections, manages data sequencing, and confirms receipt through acknowledgments, enabling applications to trust that their data has arrived intact (Stevens, 1994). TCP's flow control mechanisms, such as sliding windows, optimize bandwidth usage and prevent congestion (Jacobson, 1988).

IPv4 Subnetting and CIDR

IPv4’s 32-bit address space limits the number of assignable addresses; therefore, subnetting becomes vital to efficient IP address management (Folding, 1993). Subnetting involves dividing a network into smaller segments using subnet masks, which allocate address ranges to different subnetworks (Perlman, 1988). For instance, the assigned network 208.101.170.0/24 can be subdivided into 16 smaller subnets, enabling the organization of multiple office locations with precise address ranges.

Using Classless Inter-Domain Routing (CIDR) notation, subnets are represented with variable-length subnet masks, accommodating various network sizes flexibly (Hinden & Deering, 2017). For each subnet, necessary details include network address, subnet mask, available host addresses, broadcast address, and routing considerations. Calculations involve identifying subnet ranges, available hosts, and broadcast addresses based on borrowed bits from the host portion of the address.

Subnetting Example

Given the network 208.101.170.0/24 divided into 16 subnets, the subnet mask becomes /28, providing 16 addresses per subnet. For subnet #1:

• Network Address: 208.101.170.0/28
• Subnet Mask: 255.255.255.240
• Range of IP Addresses: 208.101.170.1 - 208.101.170.14
• Broadcast Address: 208.101.170.15
• Number of Subnets possible: 16
• Number of Hosts per subnet: 14 (minus network and broadcast addresses)

This method allows efficient IP address utilization and helps organize the network logically based on organizational needs.

Conclusion

In conclusion, understanding core networking protocols and techniques such as TCP/IP, DNS, subnetting, and software-defined networking is essential for effective cloud infrastructure deployment. Precise subnetting and IP management enable organizations like BallotOnline to maximize IP address utilization while maintaining scalable and secure networks. A strong grasp of these technologies will facilitate smooth migration and optimal cloud network design.
