7. IaaS
Providers
Oracle Cisco AWS OpenStack
OpenStack is a free, open
standard cloud computing
platform. It is mostly
deployed as infrastructure-
as-a-service (IaaS) in both
public and private clouds
where virtual servers and
other resources are made
available to users
Amazon web services is a
cloud computing platform
provided by Amazon that
includes a mixture of IaaS,
PaaS and SaaS offerings. AWS
services also offers
organizational tools such as
compute power, database
storage and content delivery
services.
Cisco brings together
network, security, analytics,
and management and
delivers a comprehensive
portfolio of multicloud
software, infrastructure,
integrated solutions, and
services to simplify how you
connect, protect, and
consume cloud in a
multicloud world.
Oracle Cloud Infrastructure
(OCI) is a deep and broad
platform of public cloud
services that enables
customers to build and run a
wide range of applications in
a scalable, secure, highly
available, and high-
performance environment.

OpenStack
Cloud guard - Service to examine Oracle Cloud Infrastructure resources
for security weakness related to configuration, Infrastructure operators,
and users for risky activities.
Data Safe - Provides a complete and integrated set of features for
protecting sensitive and regulated data in Oracle Cloud databases.
Features include Security Assessment, User Assessment, Data Discovery,
Data Masking, and Activity Auditing.
Tenancy and Compartments
Security of Data
Nondescript facilities that don't invite trouble and two factor
authentication
Routine physical access logging and auditing.
Immediate revoking of credentials when an employee (or former
employee) no longer need for access privileges.
Applications are subject to compliance regulations
Open source cloud infrastructure tools aren't always configured for
security.
OpenStack defaults typically allow for non-secure sockets layer (nonSSL)
endpoints, but this can open major security vulnerabilities in Keystone, the
OpenStack identity and authentication service.
As a result, it's crucial to add SSL encryption to Keystone instances
Cisco Umbrella provides secure access to the internet and usage of
cloud apps everywhere
DNS layer security
Secure Web Gateway
Cloud delivered firewall

Load Balancing
Application Acceleration
Expert Cisco Consultants and its channel partners guide clients in
assessing opportunities and developing and implementing the client's
unique cloud strategy
Plan-Build-Manage IT life Cycle Services
Used the development of template management technology for the easy
deployment of virtual resources on OpenStack
The benfits of this move are:
It has a mechanism of transaction management like roll back or roll
forward in case of abnormal failure during stack operations.
It shares templates among end users and System Integrators.
It extracts templates from existing environments.
It reflects actual environment changes to stack information

AWS control almost 40% of the programs running on the public cloud.
They host Apple, Netflix, Expedia, Pinterest and tons of other companies.
And when AWS servers go down the consequence is massive.
It is inevitable to prevent outages, but AWS has tactically planned data
centres such that an outage will be contained within a given region

Complete Governance over IT Services
Openstack controls large pools of compute, storage, and networking
resources, all managed through APIs or a dashboard.
Beyond standard infrastructure-as-a-service functionality, additional
components provide orchestration, fault management and service
management amongst other services to ensure high availability of user
applications.
OCI provides 3 modules to help customers optimize costs, maximize
utilization, and ensure adherence with corporate standards and
legislative compliance

AWS Well Architected franework allows to understand if a specific
architecture aligns well with AWS best practices. The framework is built
on five pillars: operational excellence, reliability, performance, security,
and cost optimization.
Responsive controls process events from cloud resources with the goal
of continuously auditing and assessing the overall compliance of AWS
infrastructure and Preventive controls are implemented as a set of
policies at the account level or organization level.

Cloud Cost Management
One major challenge faced is the fact that it is an open source cloud
infrastructure tool
The tools may be free, but the effort needed to customize, integrate, tweak
and troubleshoot open source code can make the cloud project costly and
time-consuming.
Even then, open source cloud deployments can be onerous, and
professional services or consultants are needed to help move the project
forward.
Cloud Advisor finds potential inefficiencies in your tenancy and offers
guided solutions that explain how to address them. The
recommendations help you maximize cost savings and improve the
security of your tenancy.
Cloud Advisor scans your tenancy once per day to identify specific cost-
saving recommendations. After seven days, Cloud Advisor accumulates
enough data to provide recommended actions with associated cost
savings estimates.
Pay-as-you-grow is the fundamental theory of cloud services.
Cisco adds value to it through Cloud Centre Suite
Multi-cloud spend analysis
Organize the spend
Optimize to reduce spend
Control and monitor spend
Uses Pay-as you go model
AWS free tier option
Pay less by using more
AWS also offers Savings Plans for EC2, Fargate, and Lambda

Dealing with Multi-Cloud Environments
Requirements include:
Barbican service
Access to remote Orchestration service
Template complete resources/functions compatibility
First, input remote cloud credential in a Barbican secret.
Building multi-clouds stack requires the user to build a Barbican
secret first with most information for remote endpoint information.

Cloud Migration
Since OpenStack is open source, cloud migration can happen done
through third party service providers
Database Migration is a fully managed service that helps database
administrators move databases in real-time, at scale, from one or more
source databases to Oracle Cloud databases. You have several
connectivity options when migrating your on-premises databases to the
Oracle Cloud Infrastructure.
3 Methods,

OpenStack
Unformed Technology
One of the major issues when it comes to Upgrading OpenStack comes
from the fact that it has a multi-project development approach
The complexity involved in synchronising the different projects during an
upgrade implementation may mean that downtime is unavoidable.
Oracle provides all the services and products out-of-the-box, but these
are very minimal solutions that might not be sufficient for companies
that need simple functionalities. Organizations in need of a
comprehensive platform are even less likely to get what they need.
Cloud products and services are provided as a self-contained integrated
stack
Not easy to use due to lack of enough resources on how the Oracle
cloud platform is used, unappealing and unintuitive interface.
Cisco's R&D thrives on the principle of 'Meraki'
It has Innovation centres across the continents
Collecting the unobtainable
VR Solutions
Revolutionizing Retail
Pioneering the road to rural connectivitry
AWS is introducing Data flywheel which is a comprehensive and
additive approach for business and technology leaders to enable
organizations to get the most value from their data.
Amazon MemoryDB for Redis is an in-memory database service that
delivers ultra-fast performance. It is purpose-built for modern
applications with microservices architectures.

Cloud Integration
Ultimately, deploying an open source cloud infrastructure platform and
integrating different front- and back-end components requires significant
knowledge of hardware and software.
Changes to any element can impact the entire cloud environment.
Integration is a huge project that takes a team to implement properly, and
additional staffing may be needed.
Oracle Integration Cloud (OIC) is a platform which integrates across
cloud and on-premise applications. It simplifies connectivity between key
3rd party enterprise applications and on-premise applications. The
platform offers enterprise-grade security, no hand-coding required and
governance capabilities.

integration analytics, along with data migration and integration.
Cisco Cloud Fusion enables customers to enjoy the best of on-premises
solutions and the best of the cloud.
Cisco Cloud Fusion brings together clouds and fuses applications that are
cloud-based with those on-premises, making them manageable and
secure.
Amazon AppFlow is a fully managed integration service that enables to
securely transfer data between applications in just a few clicks.
Amazon MQ is a managed message broker service for Apache ActiveMQ
and RabbitMQ that makes it easy to set up and operate message brokers
on AWS.
