Evaluating Cloud Database Migration Options Using Workload Models

The database could be deployed on a database-as-a-service offered by one of several public cloud providers, or installed and configured on a virtual machine. With either option, selecting the appropriate cloud resources requires knowledge of the database workload and size. The infrastructure of the source database may impact the migration duration; if it has limited available capacity or bandwidth, then it will take longer to extract the data. An organisation may wish to upgrade the existing database hardware to speed up migration, or schedule downtime to migrate the database while it is idle. The time for the cloud migration process depends completely on the size of the organization and the diversity and complexity of its IT infrastructure.

One of the big challenges in landscape transformation is automating and optimizing transformation processes across many large infrastructure instances. This calls for a thorough analysis and testing of all data elements in the transformation. Technical migration allows businesses to leverage the cloud’s benefits without rewriting apps from scratch. With a technical migration approach, the app remains “as is,” while the OS and the database are upgraded to the cloud. Oftentimes, the cloud offers a safer digital environment compared to on-premise data centers, although you’ll still need to follow all related regulations and take action to keep the data protected on your end.

A private cloud is a small-scale cloud that a business implements and operates within its existing data center infrastructure. This demands significant financial and technical commitment, and can lack the services and scalability found in other environments. However, it can be an ideal alternative if a business needs cloud flexibility but must retain complete control over data and workloads. Rather than deploy, modify or recreate a workload, the business opts to abandon its current workload and switch to a third-party vendor’s application, often as a SaaS product.

Furthermore, all schema objects are (tables, indexes, etc.) are essentially rebuilt in the target database. We have included the size column to show the storage space consumed by the database before it was migrated. This value was provided as input to our simulation via each system’s workload model. The simulation Execution times ranged from 8 minutes for the 18GB simulation to 144 minutes for the 200GB simulation . When computing the cost, MigSim rounds the migration duration up to the nearest full hour, in line with the cost model of many cloud providers.

White House CIO Vivek Kundra coined the term “cloud-first”, referring to the practice of preferring the cloud as a first option for building programs and applications. Learn how a cloud first strategy can benefit your organization, what challenges you can expect, and critical best practices for implementing cloud first. One of the most complex aspects of a migration, especially in a large enterprise, is moving and synchronizing large volumes of data. Look at our tutorial on reducing AWS costs to optimize cloud management. Oftentimes, migrating to the cloud means creating a completely new working environment for your teams.

These snapshots are created in a matter of seconds irrespective of the size of the volume that is being copied. Instead of copying all the data in the system, NetApp Snapshots only copy the data that was changed by manipulating block pointers. Performance – migrating https://globalcloudteam.com/ to the cloud can improve performance and end-user experience. Applications and websites hosted in the cloud can easily scale to serve more users or higher throughput, and can run in geographical locations near to end-users, to reduce network latency.

The top drivers for this decision were performance and security issues (52%), followed by the temporary nature of cloud deployments (40%), and regulatory issues (21%). Oracle Cloud Infrastructure Database Migration is based on the industry-leading Oracle Zero Downtime Migration engine utilizing Oracle GoldenGate replication. One other concern with the DBLModeller evaluation is whether the sample sets of schemas used in “SQL support” section are representative of the real world.

Strauch et al. propose a novel methodology for migrating the database of an existing system to the cloud. It focuses on complex migrations where significant quantities of data exist, and the software components remain on physical in-house servers. The strengths of this methodology include its level of detail, the evaluation with large real-world systems , and the accompanying Cloud Data Migration Tool. As a result, many organisations could easily employ it to migrate their databases. Our approach complements this methodology by accurately predicting database migration and deployment costs. It is also extremely important to ensure adequate security during the actual migration process.

Some organisations have been using clouds for over a decade and are considering switching provider , while others are planning an initial migration . In either case, the most challenging component to migrate is often the database due to the size and importance of the data it contains. However, the existing cloud migration work focuses on the software components and gives minimal consideration to data. For instance, the ARTIST and REMICS cloud migration methodologies refer to the database but do not support any database specific challenges. Similarly, cloud deployment simulators like CDOSim focus only on compute resources.

It’s often said that migrating to the cloud is like moving houses, and that’s one of the most stressful life events you can go through. You prepare for a move as best you can, pile your treasured belongings on a truck, and hope they arrive at the destination. Months or even years later, you may still be wondering if a box went missing. Depending upon the application and its environment, Docker file may need few tweaks.

Adopting Oracle Autonomous Database

For users of on-premises FAS or AFF ONTAP storage systems, SnapMirror enables you to seamlessly move data to or from the cloud as necessary for ongoing hybrid environment syncs. For migrations that are being carried out from systems that are not both ONTAP, Cloud Volumes Service offers Cloud Sync to carry out the migration between any kind of object-based storage repository. Replacing is another solution to the challenges that inform the Rebuild approach. The difference here is that the company doesn’t redevelop its own native application from scratch. This involves migrating to a third-party, prebuilt application provided by the vendor.

This requires a clear and detailed understanding of the cloud provider’s resources, services and infrastructure. However, the overall features and functionality of the workload remain unchanged. With Cloud Volumes, NetApp provides several tools that help you automate, sync data faster, and secure your data while transitioning to the cloud. Cloud Volumes ONTAP storage efficiencies also help reduce network bandwidth costs during migrations by reducing storage footprint, which also accelerates data transfers. One of the first steps to consider before migrating data to the cloud is to determine the use case that the public cloud will serve. But for those making the initial foray to the cloud, there are a few critical considerations to be aware of, which we’ll take a look at below.

Migrate Applications And Data & Review

Find out the details of some of the major changes and how it affects Kubernetes users Kubernetes, particularly when it comes to managing persistent storage. The last update of 2021 brought some big changes to how Kubernetes works. Kubernetes 1.23 brought with it 47 enhancements to Kubernetes, including a host of stable enhancements, a number of features moving into beta, some all new alpha features, and one notable deprecation.

The impact of this extra performance can be seen in Table4 and 5 as the migration time is not proportional to size. The Workload Model specifies historical growth trends and usage patterns. This data must be extrapolated to predict the future database traffic if these trends continue. The storage space consumed by the database in the future is dependent on the amount of new data inserted. Furthermore, the provisioned database throughput required depends on future database traffic. We have used linear regression, specifically the ordinary least squares method , to estimate the number of future read and write queries received by the database.

This ensures that, from an application or end-user perspective, there is no downtime as there is a seamless transition to the secondary storage in case the primary storage fails. Scalability – cloud computing can scale to support larger workloads and more users, much more easily than on-premises infrastructure. In traditional IT environments, companies had to purchase and set up physical servers, software licenses, storage and network equipment to scale up business services. The key factors affecting the cost of migration include data storage, processing capabilities, security, testing, and monitoring tools. Perform a comprehensive functional and technical assessment of your system and then create a step-by-step plan for your migration project.

The code, experimental data, and results are publicly available in our GitHub repositories at for DBLModeller and for MigSim to enable replication. It should also be noted that migrating databases from ERP systems is an expensive and time consuming process. While we made full use of our systems by migrating them twice, experiments on other systems should performed to confirm our encouraging findings.

Businesses typically choose a provider based on the scope of services offered and any specific functionality for a given workload. For example, AWS offers a wide array of prepackaged computing instances, while Google Cloud Cloud data migration is noted for its machine learning and artificial intelligence services. Comparing the predicted costs from our approach with those from the existing cloud cost calculators shows an increase of between 53 and 60% .

This is due to over-provisioning as the calculators do not use workload information to select the required cloud resources. Cloud cost calculators are typically intended to produce cost estimates for short periods, where the resource requirements are known. However, migrating large growing database to the cloud requires a more sophisticated approach to determine costs. We have shown that MigSim can accurately predict when the database infrastructure requires scaling, and therefore the number of database instances that must be running. Relational databases are prevalent in the cloud migration literature, and they are therefore the focus of our work. However, the approach (Fig.1) does not have a strict dependency on one database type.

The SQL schemas and models used in our evaluation are available at the same location. We are unable to release the Science Warehouse SQL schema as this is proprietary. Similarly, the Science Warehouse KDM structure model has not been released as it could be used to recreate the SQL schema. By default our approach produces cost estimates based on the assumption that the observed load trends in the model will continue. The growth rate can also be manually adjusted to accommodate business plans. The results in Table6 use this functionality to produce the 5 and 40% growth rates.

Learn about the importance of a cloud roadmap in migration projects, questions you should ask when building your roadmap, and the five key sections of a cloud roadmap. Rebuilding takes the Revise approach even further by discarding the existing code base and replacing it with a new one. This process takes a lot of time and is only considered when companies decide that their existing solutions don’t meet current business needs. Every business journey is unique, and your project may include elements of different cloud migration techniques at various stages of its lifetime.

How To Get Cloud Migration Strategy Right: Dos And Donts

Refactoring — redesigning applications and rewriting significant portions of the code. The implementation’s success will depend on the organization’s ability to replicate its workflows, which requires thorough knowledge of the company’s current infrastructure. Try the only feature-complete, enterprise-class Cloud PAM solution in the world. When you end up on the other side with a more streamlined, more cost-efficient PAM solution, you’ll be glad you did. As your organization grows and becomes more globally distributed, you won’t need to worry about managing as many incoming connections into your network to access your PAM solution. PAM systems are designed to keep things in—not out—so migration can feel unnatural and maybe even a little scary if you’ve never done it before.

Below, let’s take a close look at the most common mistakes in cloud migration, and share tips on how to avoid cloud migration pitfalls at each step of the process. System conversion is an effective approach for organizations looking to bring their business processes to a new platform and add extensive new features while keeping their existing customizations. In contrast to modernizing old systems, the organization can choose a new suite of applications to go into, regardless of their current environment or vendor. Replatforming allows businesses to optimize their apps for cloud-native capabilities. Businesses can start small, test things out, and scale without investing many resources in the short term. We’ve developed a step-by-step methodology that takes the fear and stress out of your cloud migration.

If there is extremely less data to migrate, then enterprises can just copy their data over a simple Internet connection. To avoid these issues, enterprises can decide to compress their data before they send it. Alternatively, they can ship their data in a physical form to the cloud service provider to save costs related to bandwidth.

Pam In The Cloud Vs Pam For The Cloud Whats The Difference?

This threshold remains constant in every simulation, although it is reached at time moments that depend on the growth rate (sooner for high growing rate, as shown in Fig.7). In this definition, a query is a typical CRUD SQL query for an ERP system. The calibration between published database performance and typical database queries per second is a fixed-ratio.

Public cloud users generally consume these services in a pay-per-use model. Digital experience – users can access cloud services and data from anywhere, whether they are employees or customers. This contributes to digital transformation, enables an improved experience for customers, and provides employees with modern, flexible tools. Cloud migration promises many advantages — scalability, stability, and ease of business innovation are among them.
