Amazon Web Services vs. Microsoft Azure vs. Vertex

This is something that is actually common across most cloud providers. A comprehensive understanding of one's use cases, constraints and future directions is key to determining if you even need a cloud solution. If you are a 2-person startup developing something with a best-scenario audience of 1k DAU in a year, you would very likely best served by a dirt-cheap dedicated Linux server somewhere (and your options to graduate to a cloud solution will still be open). If, however, you are a bigger fish, and/or you are actively considering build-vs-buy decisions for complicated, highly-loaded, six-figure requests per minute systems, global loadbalancing, extreme growth projections - then MAYBE you solve all or part of it with a cloud provider. And depending on your taste for risk, reliability, flexibility, track record - it might be AWS.

Azure is particularly well suited for enterprise environments with existing Microsoft investments, those that require robust compliance features, and organizations that need hybrid cloud capabilities that bridge on-premises and cloud infrastructure. In my opinion, Azure is less appropriate for cost-sensitive startups or small businesses without dedicated cloud expertise and scenarios requiring edge computing use cases with limited connectivity. Azure offers comprehensive solutions for most business needs but can feel like there is a higher learning curve than other cloud-based providers, depending on the product and use case.

I have used Vertex since the very beginning of my career. I have always found the information clear, and easy to use. The documentation to use the product was thorough. We file returns in all 45 states that have sales / use taxes and having the ability to import data, key additional data in and print out a signature ready return has made life easy. I've never wanted to look at any other return preparation software as none of them come close to the product that Vertex created.

• During the month-end, we experience high resource utilization; however, with AWS's scalability, we can effectively tackle the peak load.
• With AWS IAM, we don't need to set up complete infrastructure for identity and access management, as AWS provides end-to-end IAM services.
• With AWS, development has become very easy as it's very quick to spin up and destroy the environment, which saves costs.

Incentivized

• Microsoft Azure is highly scalable and flexible. You can quickly scale up or down additional resources and computing power.
• You have no longer upfront investments for hardware. You only pay for the use of your computing power, storage space, or services.
• The uptime that can be achieved and guaranteed is very important for our company. This includes the rapid maintenance for security updates that are mostly carried out by Microsoft.
• The wide range of capabilities of services that are possible in Microsoft Azure. You can practically put or create anything in Microsoft Azure.

• Vertex does a great job of building in-house industry expertise (leasing in our case) so they truly understand the tax technical and compliance obstacles we face day to day.
• Vertex actively solicits for and responds to customer feedback on development and product roadmap suggestions. The Leasing users group is an example where Vertex takes an active role in communicating with and taking feedback from our industry.
• Vertex tax updates are very timely and thorough, which makes the compliance process less stressful for our team.

• When there is any misconfiguration of EC2 related to SSM Connect. It doesn't clearly states that what particular configuration is missing.
• Debugging networking related issues could be improved.
• From the security group page, it's difficult to determine which resource a security group is associated with.

Incentivized

• The cost of resources is difficult to determine, technical documentation is frequently out of date, and documentation and mapping capabilities are lacking.
• The documentation needs to be improved, and some advanced configuration options require research and experimentation.
• Microsoft's licensing scheme is too complex for the average user, and Azure SQL syntax is too different from traditional SQL.

• Reporting: Vertex VAT Compliance is not fully ready to support all EU country's requirements.
• Data storage.
• Online reporting in VVC: many countries require to report VAT Declaration in an electronic way. This function is still missing for some of the countries from VVC.

We are almost entirely satisfied with the service. In order to move off it, we'd have to build for ourselves many of the services that AWS provides and the cost would be prohibitive. Although there are cost savings and security benefits to returning to the colo facility, we could never afford to do it, and we'd hate to give up the innovation and constant cycle of new features that AWS gives us.

Moving to Azure was and still is an organizational strategy and not simply changing vendors. Our product roadmap revolved around Azure as we are in the business of humanitarian relief and Azure and Microsoft play an important part in quickly and efficiently serving all of the world. Migration and investment in Azure should be considered as an overall strategy of an organization and communicated companywide.

We are satisfied with the overall performance of Vertex. The software has provided my company with many efficiencies. We have shorted our audits and found that many audits are happy that we are using Vertex to calculate our taxes. We no longer need to worry about updating our rates each month since Vertex sends us a file to upload

AWS offers a wide range of powerful services that cater to various business needs which is significant strength. The ability to scale resources on-demand is a major advantage making it suitable for businesses of all sizes. The sheer volume of options and configurations can be overwhelming for new users leading to a steep learning curve. While functional the AWS management console can feel cluttered and less intuitive compared to some competitors which can hinder navigation. Although some documentation lacks clarity and practical examples which can frustrate users trying to implement specific solutions.

As Microsoft Azure is [doing a] really good with PaaS. The need of a market is to have [a] combo of PaaS and IaaS. While AWS is making [an] exceptionally well blend of both of them, Azure needs to work more on DevOps and Automation stuff. Apart from that, I would recommend Azure as a great platform for cloud services as scale.

Vertex itself is very good software. Its tax calculation is very accurate, and there should be no doubt whether Vertex is calculating the tax. Customer support is also good, and the response is quick. The updates are also good and easy to understand, making this an excellent application.

Availability is very good, with the exception of occasional spectacular outages.

It has proven to be unreliable in our production environment and services become unavailable without proper notification to system administrators

I have always felt VERTEX support was available when needed, and I have felt comfortable calling in some heavy hitters when needed

AWS does not provide the raw performance that you can get by building your own custom infrastructure. However, it is often the case that the benefits of specialized, high-performance hardware do not necessarily outweigh the significant extra cost and risk. Performance as perceived by the user is very different from raw throughput.

Our Vertex performance is good, although we are now experiencing Error 502 when adding additional data points to our transaction tester single tests. At Exchange, I was told to reach out to support....that most likely the On Demand system needed some additional CPU resource added. I have a currently open ticket, that has not yet been fixed on this matter

The customer support of Amazon Web Services are quick in their responses. I appreciate its entire team, which works amazingly, and provides professional support. AWS is a great tool, indeed, to provide customers a suitable way to
immediately search for their compatible software's and also to guide them in a
good direction. Moreover, this product is a good suggestion for every type of
company because of its affordability and ease of use.

We were running Windows Server and Active Directory, so [Microsoft] Azure was a seamless transition. We ran into a few, if any support issues, however, the availability of Microsoft Azure's support team was more than willing and able to guide us through the process. They even proposed solutions to issues we had not even thought of!

Incentivized

Level 1 support has always been kind and understanding but times they do not always provided the technical help sometimes their response or protocol is not related. I feel that I have to beg for a developer to look over my issue. On the other hand, there have been times a Level 1 support person has taken the time to research my issue and provide valid feedback & solution

By training I'm referring to our engagement with Vertex Consulting's professional services group. Each person on the engagement had prior leasing industry tax experience and most if not all used O Series before joining Vertex. Consultants with industry specific tax experience provide so much more than just "training". They are able to engage in deep tax technical discussions with actual experience while in private practice. This coupled with having visibility to how numerous other leasing peers approach similar tax issues is a huge plus on top of the standard training.

Vertex has offered multiple webinars for the products we have purchased that are informative and helpful. I've also attended a few of the Vertex annual conferences where I was able to strength my knowledge of Vertex. I also found that their online library and videos can be helpful in resolving issues and answering questions.

The API's were very well documented and was Janova's main point of entry into the services.

As I have mentioned before the issue with my Oracle Mismatch Version issues that have put a delay on moving one of my platforms will justify my 7 rating.

The implementation is challenging, make no mistake but will provide much value over time. Make sure you have full support of IT and your major stakeholders in your company. I found that while many people claimed to understand tax was important, they had no idea how deep tax in entrenched throughout the lease life cycle.

Amazon Web Services fits best for all levels of organisations like startup, mid level or enterprise. The services are easy to use and doesn't require a high level of understanding as you can learn via blogs or youtube videos. AWS is Reasonable in cost as the plan is pay as you use.

As I continue to evaluate the "big three" cloud providers for our clients, I make the following distinctions, though this gap continues to close. AWS is more granular, and inherently powerful in the configuration options compared to [Microsoft] Azure. It is a "developer" platform for cloud. However, Azure PowerShell is helping close this gap. Google Cloud is the leading containerization platform, largely thanks to it building kubernetes from the ground up. Azure containerization is getting better at having the same storage/deployment options.

In comparison specifically with Avalara, Vertex is better in every way. It is much more customizable and allows us to change the way our tax software is set up for our business needs. Avalara is much more constricted, and is using the SST system which can allow for simplified returns, but in our case was causing more problems. Avalara is also much more expensive than Vertex, for less capabilities. Vertex' customer support is much stronger than Avalara's, as they are focused on obtaining and retaining customers whereas Avalara was continually trying to find ways to get money from us

There needs to be a time-consuming setup both in the Enterprise Resource Platform and in Vertex and the related tools as well but once this is all established, Vertex is very proficient at calculating Sales and Use Tax in the USA and in Canada with GST/HST, as well as several of the provinces where we are located. As we added plants in different jurisdictions via greenfield expansion and aquisition, Vertex was able to integrate those as long as the tax department is fully informed of the system.

• Using Amazon Web Services has allowed us to develop and deploy new SAAS solutions quicker than we did when we used traditional web hosting. This has allowed us to grow our service offerings to clients and also add more value to our existing services.
• Having AWS deployed has also allowed our development team to focus on delivering high-quality software without worrying about whether our servers will be able to handle the demand. Since AWS allows you to adjust your server needs based on demand, we can easily assign a faster server instance to ease and improve service without the client even knowing what we did.

• For about 2 years we didn't have to do anything with our production VMs, the system ran without a hitch, which meant our engineers could focus on features rather than infrastructure.
• DNS management was very easy in Azure, which made it easy to upgrade our cluster with zero downtime.
• Azure Web UI was easy to work with and navigate, which meant our senior engineers and DevOps team could work with Azure without formal training.

Incentivized

• We use Vertex on a monthly basis to see if tax has been over-accrued or over-charged on invoices. We do save tax every month using the tool. Not at liberty to share too much more - the technology does assist the human efforts.
