БҰЛТ ОБЛАКО CLOUD A cloud is a virtual environment (cloud service) in which
you can run virtual computers (servers) that can be
accessed remotely.
ҚОҒАМДЫҚ БҰЛТ ПУБЛИЧНОЕ ОБЛАКО PUBLIC CLOUD This is the infrastructure that allows you to store your
data on the Internet on servers that also remain available
to other B users. This number of users is limited. The
cost of a public cloud depends on the amount of data
you store on the server. You pay as much as you keep.
This type of cloud service offers its users an almost
infinite amount of data
ЖЕКЕ БҰЛТ ЛИЧНОЕ ОБЛАКО PRIVATE CLOUD As the name suggests, it remains the property of the
object. It is most often a type of cloud suitable for
businesses that need complete control over their data,
software, and applications that are stored on their
servers. These servers may be located directly outside
the company building. Servers can also be managed by
an external service provider used.
ГИБРИДТІК БҰЛТ ГИБРИДНОЕ ОБЛАКО HYBRID CLOUD Some companies have started using this type of cloud.
Indeed, a hybrid cloud is a combination of a private and
a public cloud. This cloud service remains the
prerogative of large companies that solve specific needs.
When they work, they use two types of data (confidential
and non-confidential). Confidential bank and other data
remain in the public cloud, from where anyone can
access it.
4. WHAT IS AN INTERNET CLOUD?
Cloud computing is used for business, education, and private life.
Sending e-mail, online documents, storing photos from a smartphone,
watching videos - it's all in the cloud.
In simple words, the cloud on the Internet provides any user with quick
access to flexible and low-cost IT resources. Instead of investing
resources in hardware, hosting,and maintainingit, you can get any
type and amount of computing resources in cloud services.

HYBRID
04 A distributed system that integrates the services
of various clouds. This approachallowsyou to
meet the needs of a particular industry or
community. The infrastructure is divided among
organizationsthat have common problems or
tasks. There are two management options - by
the community itself or by a third party (provider).
COMMUNITY
6. SERVICES IN THE CLOUD
Infrastructure as a service. The tenant
uses the provider's IT resources: servers
with OS and network access. The client
installsallnecessary software
independently.
IaaS
software as a service). You can use
any licensed software without
buying it. The software is updated
on the provider'sside, which saves
the tenant's budget and time.
SaaS
Platform as a service. Inthis model, in
additionto the infrastructure, the
operating system, software, DBMS, and
specialized software for development
and testing willbe installed on the
server.
PaaS
Function as a service). Blocks of code with narrow
functionality are configured to run on a specific
event. This gives you the opportunity to lower
your actual consumed resource charges because
FaaS applicationsdo not consume IaaSresources
until an event occurs.

7. The cloud is
profitable and
convenient for
businesses. What
do users who
work in cloud
services get:
1. Reduced variable costs. No need to buy physical equipment, maintain and upgrade it, or
hire staff. You can pay only for the use of computing resources and their actual
consumption. Data from many customers is collected in the cloud, which enables
providers to achieve higher economies of scale, which means lower prices for cloud
services for consumers.
2. Using only the necessary resources. Allthe features of the cloud can be scaled: increase
the amount of storage space, and add RAM. Tenants are not limited by the physical
resources of their infrastructure - you can reduce and increase resource parameters in
one click.
3. High speed and flexibility. In the cloud, you can get the necessary IT resources in a few
minutes. For example, instead of buying licensed software, you can rent it in the cloud -
it's faster. Just as quickly, you can bring your software to the consumer - deployment is
faster than using physical machines.
4. No need to equip and maintaina server room. Leveraging the cloud allowsyou to focus
on core business objectives rather than buying and hosting racks, stacks, power, and
cooling.
8. ADVANTAGES
Flexibility. Scales on demand to support
changing workloads.
Variety of storage options. Users can
choose from public, private, or hybrid
offerings based on their security needs,
industry, and business objectives.
1
Choice of what you need. The level of control is
defined using the "as a service" options:
infrastructure, platform, software, and operation as a
service. You can choose from a menu of ready-made
tools and functions that cover specific needs.
2
Safety. Virtual private cloud, encryption,
and API keys help keep your data
secure. Hardware failures do not lead to
information loss due to online backups.
Availability. Cloud applications and data
are accessible from virtually any
internet-connected device.
3
Product output speed. Workingin the
cloud allows developers to quickly
bring their applications to market.

10. DISADVANTAGES
Service outages are rare, but they do happen. Most providers place
servers in aTIER IIIlevel datacenter, where the equipment is reliably
protected from any kind of external damage and hacker attacks, but
problems still happen. In addition,access to the cloud is implemented via
the Internet, which means it depends on the speed and stability of the
connection.
DOWNTIME
Cloud security is both high and low. What
does it mean? Security issues should be
dealt with by both parties: the provider and
the tenant. Often, tenants pay little
attention to this: they do notinstall a
Firewall, and do not use fine-grained access
settings.

Perhaps the main drawbackof the cloud.
Differences between provider systems can be so
significant that the transition from one cloud
platformto another becomes impossible.
Migration between platforms exposes datato
additionalsecurity and privacy vulnerabilities.
SUPPLIERBINDING
The control and functions of the infrastructure are detailed in the SLA. It
is imperative to read the license agreement - it is in it that pitfallsfor
tenants can be hidden, for example, limiting management policies. The
agreement may include full control over applications,services, and data,
but not the backend.For some companies, this can be a problem.
