Benefits of Migrating Enterprise Applications to the Cloud:

Cost Savings

Reduced Costs on IT Infrastructure: They do not directly invest in comericial equipment and services such as on-site hardware (servers, storage, networking equipment) and data centers and their cooling systems

Pay-as-You-Go Model: Most cloud providers align this cost on the actual usage to enable the up or down scaling on cost outlay.
-Rapid scaling: Optional users may be increased or decreased instantly in response to a range of rarely occurring or unpredictable high levels of demand, for example at the end of calendar years, academic years or fiscal years. Faster time to market: The fast deployment of applications and services ensures that new products/services are developed and launched on the market faster.

Higher Innovation
-Access to Cutting-Edge Technologies: Get more access to the cloud services, such as AI/ML, big data and IoT, to transform business models for growth.
-Focus on Core Business: Divert IT infrastructure responsibilities and workload leaving room for IT to deliver more on strategic concerns that supports the business.

Improved Security:
-Strong Security: Cloud providers invest a lot of money in security and its deployment and follow the best practices to shield data and applications from threats.

Difficulties in Migrating Enterprise Applications to the Cloud:

Security:
Data Breaches: The cloud providers may offer strong protection measures but there are still data leaks.
Compliance Issues: Implementing privacy rules for data storage sharing particularly in the current increased cloud utilize (for example the GDPR or CCPA ).

Vendor Lock-in:
Dependence on the Cloud Provider: Data and applications are moved to a specific cloud provider and this make it complex to do the same with another in future hence creating vendor lock in.

Integration Challenges:
Integration with Existing Systems: However, they also posed some important challenges that include the following: The integration of the cloud-based applications with the existing on site systems and applications is always a challenge.

Cost Management:
Unexpected Costs: The following costs are also possible if not checked frequently; data transfer charges, storage fees, and the emergence of surge in usage among others.

Data Migration:
Data Quantity: Heavy volume data migrating into the cloud will be complex and time-consuming potentially causing disruption to daily business routines.

Skilling Gap:
-Cloud Savvy: For successful handling and management of applications powered through cloud, organizations must build their skills.
