Print
Begin Right here
In CCA 610: Cloud Companies and Know-how, you assumed the role of an IT analyst
at BallotOnline, a firm offering digital voting options worldwide. Your
proposal to start migrating methods to the cloud has been authorized.
BallotOnline has now initiated preparations for the cloud deployment. The
firm determined to begin with deeper investigations of essential applied sciences
enabling cloud computing. You grew to become acquainted with the fundamentals of these
applied sciences in CCA 610.
On this challenge, you will conduct extra in-depth investigation of cloud networking,
which makes cloud connectivity on-demand operations potential. You have to have
a good understanding of this as you put together the BallotOnline network for migration
to the cloud in addition to designing the applicable network infrastructure in the
cloud for BallotOnline.
To do that, you will assume the role of a BallotOnline network engineer. You will
discover the network protocols that allow the firm and its prospects to
hook up with the cloud, in addition to applied sciences making it potential to create ondemand in-cloud digital networks into which the cloud assets will be deployed.
Step1: Assessment Networking Ideas
On this step, you will set up an understanding of networking ideas and phrases.
It will Help the recipients of your technical report, together with BallotOnline’s technical
administration, to turn out to be accustomed to networking vocabulary and definitions.
You will begin with reviewing fundamental networking ideas corresponding to native space network
(LAN), Ethernet, and packet switching—the method of splitting transmitted knowledge
into smaller parts and transmitting them individually.
Splitting knowledge into packets, transmitting the packets reliably, and reassembling the
knowledge is carried out by networking software program. You will need to learn about fundamental
networking ideas since they function the underlying know-how for cloud
computing. This will in the end put together you to submit your technical report for this
challenge.
Networking software program follows the common mannequin of layered design of network
protocols, with every layer utilizing the performance of the layer beneath it and
implementing new performance for use by the layer above. The technical report
ought to embody the common web suite of protocols—TCP/IP. Utility
protocols corresponding to HTTP or SMTP are carried out in layers above TCP/IP.
Different fundamental networking ideas embody Area Identify Service, network firewalls,
and Network Deal with Translation. As the network engineer for BallotOnline, you
know that these protocols play an essential role in enabling cloud computing.
Now that you have accomplished your overview, transfer to the subsequent step, the place you will
take a nearer have a look at the essential protocol of the web.
Step2: Discover Web Packet Switching—IP
The Web Protocol (IP) is the workhorse of as we speak’s web connectivity. As the
network engineer for BallotOnline, you know that as we speak’s cloud computing is constructed
on prime of IP. Most communication between methods in the cloud is completed utilizing this
protocol.
IP employs the method of packet switching, which breaks the knowledge to be
transmitted into smaller components, referred to as packets or datagrams, which might be despatched over the
network independently. Understanding IP is essential to designing and sustaining
cloud deployments, that are provisioned inside digital IP networks and accessed
by way of world web. You will evaluate the fundamental components of IP protocol and embody
their temporary dialogue in your technical report.
Network gadgets have a network deal with to permit different gadgets to hook up with it.
The network addresses utilized in IP are referred to as IP addressing. BallotOnline will want
IPv4 addressing to have the ability to present network addresses to a cloud system and to
create a digital network in the cloud.
Each system on the network will need to have an IP deal with. The assignments of IP
addresses to the network methods could be executed manually or dynamically by way of
a Dynamic Host Configuration Protocol (DHCP) server. As the network engineer
for BallotOnline, you know that manually assigning IP addresses is time-consuming
and will solely be used on a small quantity of methods the place the IP deal with will
not change incessantly.
As a result of numeric addresses usually are not human-friendly, a area/machine naming
conference defines human-readable names for web hosts. An online-based
service referred to as DNS (Area Identify System) gives translation between the IP
addresses and the domains. Normally, folks will use the domains
when addressing a system on the web as a substitute of utilizing its IP deal with. You will
want to clarify in the technical report how DNS is used alongside IP addresses.
As the network engineer for BallotOnline, you additionally know the significance of IP
routing, the mechanism used to route the IP packets throughout the web from the
sender to the recipient. IP routing of IP packets is achieved by network
routers, which decide the subsequent vacation spot for every packet and are in a position to be taught
new routes.
In the subsequent step, you will take a nearer have a look at Transmission Management Protocol (TCP),
one other key cloud element.
Step three: Examine Web Transport—TCP
As sturdy as the IP protocol is, it doesn’t carry out the precise transmission of the
knowledge. On this step, you will examine the network protocol referred to as Transmission
Management Protocol (TCP), liable for creation, reliability of supply, and correct
assembling of knowledge packets.
Along with IP, TCP can be broadly used on the web, particularly for any network
communication the place it’s important to substantiate receipt of the transmission. Many
of the network protocols used to implement cloud computing use each TCP and IP.
You will evaluate TCP’s workings and focus on them in your remaining technical report.
Normally, there isn’t any assure that a knowledge packet will attain its vacation spot.
Packets can get misplaced or corrupted throughout transmission, and there are network
purposes the place you want assurance that the packets have reached their
vacation spot. To obtain reliability, TCP establishes connections between
speaking hosts, utilizing port numbers to seek advice from purposes on these hosts.
Then, packets are created, sequenced, transmitted, acknowledged, and
retransmitted if lacking or containing errors. Lastly, at the vacation spot, they’re
reassembled into the unique messages.
To synchronize the movement of packets between sender and receiver, and keep away from packet
congestion in case of various speeds, TCP makes use of sliding home windows for packets
remaining in processing at a given time, at each the sender and receiver ends.
In the subsequent step, you will look into subnetting BallotOnline’s IP addresses.
Step four: Assessment Benefits of IP Subnetting
One of the drawbacks of IPv4 is the most quantity of network gadgets it may well
help. IPv4 addressing makes use of a 32-bit network deal with. This enables for 232,, or a
little over four billion gadgets. Nevertheless, as we speak there are considerably extra gadgets on
the web. Despite the fact that the extra sturdy IPv6 model has been launched and
efforts are underneath solution to guarantee vast adoption, IPv4 continues to be broadly used.
One technique used to extra effectively use the IPv4 network addresses is a
method to optimize the addresses by splitting them into network addresses and
host addresses inside designated networks. You will have to take benefit of IP
deal with splitting in order that you can effectively use and allocate the IPv4 network
addresses which were assigned to BallotOnline.
For a given giant network, fairly than addressing all the hosts utilizing the host half
of the deal with, subnetting permits for splitting the network into a number of smaller
ones by borrowing the host half bits and including them to the network bits. It
helps environment friendly administration of native networks composed of a number of LANs. In
this step, you will examine subnetting conventions and focus on them in your
remaining report to be able to lay floor for the use of subnets by BallotOnline.
As the network engineer for BallotOnline, you know that subnetting a network into
a number of smaller and variable-sized networks will be finest for the group’s
wants. BallotOnline has been assigned a network deal with block by the Web
Assigned Numbers Authority (IANA).
As a result of BallotOnline has a number of workplaces round the world, you will have to subnet
this network deal with to assign simply the proper quantity of addresses to every workplace
location primarily based on the quantity of methods at that workplace location (the network
deal with assigned by IANA and the quantity of workplaces together with their sizes will be
offered in the announcement part of this class at the starting of Week 2).
Your process is to create the applicable quantity of subnets with the proper dimension to
optimize the network.
Your technical report ought to embody Classless Interdomain Routing
(CIDR) notation, which permits for specifying a variable-length network as half of
the IPv4 deal with, leaving the relaxation for addressing hosts inside the network.
Submit the network info in the submission field beneath.

Discover Networks Inside the Cloud—SDN
Cloud computing defines network assets as needing to be “quickly provisioned
and launched with minimal administration effort or service supplier
interplay” (Mell & Grance, 2011), As cloud networks developed, it was clear that
additional virtualization of network gadgets corresponding to switches and routers was wanted.
This led to what’s referred to as software-defined networking (SDN) know-how,
enabling programmatic interfaces to manage features of these gadgets. You know
that it will be essential for administration to know how SDN helps cloud
deployments like BallotOnline’s, so it will be a key half of your technical report.
As an alternative of manually programming network gadgets to configure a LAN, cloud
administration methods utilizing SDN can set these gadgets as much as ahead packets to
specific locations by “calling” SDN APIs (utility programming interfaces
– libraries of software program routines). This enables for the creation of digital networks in
the cloud by software program.
The preferred SDN normal is OpenFlow by the Open Networking
Basis. OpenFlow switches embody SDN controllers, which keep movement
tables to manage forwarding of IP datagrams, and so they can be taught routes as IP
packets when specific supply and vacation spot addresses arrive.
