Proficient in modern technologies including ReactJS, NodeJS, GraphQL,
TypeScript
In-depth knowledge of cloud cost optimization techniques and strategies
Proven experience in cloud migration and deployment
Skilled in cloud security and data management
Familiar with cloud monitoring and analytics tools, such as Amazon CloudWatch
Knowledge of cloud resource management tools, such as AWS Auto Scaling or
Kubernetes

Cloud Storage

3. Cost Savings
Cloud computing saves infrastructure,
maintenance, and support expenses
Scalability
Cloud computing lets businesses scale
up or down without adding hardware
Disaster Recovery
Improved Security
The cloud helps organizations recover from
natural catastrophes and hardware faults
Cloud service providers have data security
teams and invest heavily. This improves
security over on-premises systems.
1. Importance of
cloud migration
There are several reasons why cloud migration has
become increasingly important for businesses:
Flexibility
Cloud computing allows remote work by
providing data and applications through
the internet

4. Lack of Strategy
Unplanned cloud migration is common.
Cloud transfer methodologies differ per
application and dataset.
Cost Management
Several companies lack cloud migration
KPIs. Measuring economic migration
success is difficult.
Data Security and Compliance
Vendor Lock-In
Cloud migration risks include data security,
compliance, and configuration
responsibilities for organizations.
Cloud adopters face vendor lock-in,
incompatible services, costly migration,
and switching struggles.
2. Common Cloud
Migration Challenges
Here are some of the major challenges facing many
organizations as they transition resources to the cloud:

5. 3. Cloud Migration
Preparation
Cloud migration requires infrastructure review. This test will
help you move, leave, and change. Assessment:
01
InventoryYourExistingEnvironment: List
all servers, storage devices, databases, and
applications in your environment.
02
EvaluateApplicationPerformance:
Assess each application's performance
and resource use to discover which ones
require cloud optimization.

6. 03 For example: what data each program
generates, performance needs, and backup
frequency.
DetermineDataRequirements: Assess each
application's data needs, including storage,
bandwidth, and computing power.
04
AssessSecurityandCompliance
Requirements:Check whether the cloud can
meet your security and compliance needs.

7. 05 Web applications and databases may
rely on one other.
Check third-party APIs and services for
cloud compatibility.
DetectApplicationDependencies:
Find database connections, shared storage,
and network setups.
06
EvaluateCost:Compare the expense of
sustaining your present environment
versus switching to the cloud. This will
help you assess cloud migration costs.

5. Cloud Migration Strategies

10. 5.1 - Lift and Shift
Moving apps and data to the cloud without changing architecture or design is this method. Simple migrations to
the cloud employ this method, which is the fastest.

11. 5.2 - Re-architecting
To use cloud functionalities, this technique entails changing application architecture or design. Complex
programs employ this method, which may save money and enhance performance.

12. Reduce Costs of Ownership
Cloud VMs cost less than on-premise,
with further cost savings from containers
and serverless computing.
Achieve Application Resilience
Cloud microservices have built-in fault
tolerance for partial functionality during
rare failures with quicker recovery time.
Drive Agility with the Cloud
Enable Scalability
Cloud-native apps use microservices for
agile management via DevOps with
continuous integration and delivery.
Cloud auto-scaling and serverless
computing enable elasticity for efficient
resource allocation and cost reduction.
5.2 - Reasons to Re-Architect
Applications for the Cloud

13. 5.3 - Hybrid Cloud
This method includes cloud and on-premises workloads. This method lets enterprises employ both
environments for disaster recovery and compliance.

14. 5.3 - Hybrid cloud pros and cons
01 Bettersupportforaremote

02 Improvedscalabilityandcontrol
03 Businesscontinuity
04 Improvedsecurityandrisk

07 Lackofvisibility

15. This technique entails creating cloud-based software from scratch.
This method lets companies make use of the newest cloud services
and capabilities and support new business objectives.
5.4 - Greenfield Strategy

16. 5.4 - Greenfield Strategy: Pros and Cons
+ Gives an opportunity to implement a state-
of-the-art technology solution from scratch
+
+
-
-
-
Provides a clean slate for software
development
No compulsion to work within the constraints
of existing systems or infrastructure
With no clear direction, the degree of risk is
comparatively higher
Since all aspects of the new system need to
be defined, it can be quite time-consuming
With so many possible development options,
there may be no clear understanding of the
approach to take
+
No dependencies or ties to existing software,
preconceived notions, or existing business
processes

17. 6 - Real-World Examples of Successful
Cloud Migration
Spotify:Spotify migrated its music streaming
service to the cloud, using Google Cloud.
Netflix:Netflix migrated its entire infrastructure
to the cloud, using AWS.
CapitalOne: To boost agility and innovation,
Capital One moved its infrastructure to AWS and
Azure.
Dropbox: Dropbox migrated its infrastructure from
its own data centers to the cloud, using AWS.
