Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.9
AWS offers cost savings, scalability, and agility with a pay-as-you-go model, attracting clients and reducing overhead.
Sentiment score
4.9
Google App Engine can reduce costs significantly but results vary based on user familiarity and organizational deployment.
Sentiment score
7.5
Salesforce Platform enhances efficiency, reduces information silos, boosts revenue growth, and cuts client data management time by up to 50%.
Once we deployed this same application as part of Google App Engine, the cost drastically reduced to just $120 for the small instance we use for our development.
Operationally, it was efficient for us because we could easily spin up new versions to demonstrate new functionality without modifying the original environment.
I have noticed a return on investment in terms of less maintenance, but it depends on the organization's standard deployment preferences.
Salesforce saved about 40% to 50% of my time by allowing me to manage and maintain client data and account progress.
 

Customer Service

Sentiment score
6.9
AWS is favored for reliable support and problem-solving despite concerns over response times and communication efficiency.
Sentiment score
6.0
Google App Engine's customer service experiences vary, with responses ranging from efficient support to delays and reliance on documentation.
Sentiment score
6.7
Salesforce Platform generally provides solid support, but response times vary, with users appreciating community resources and premium service benefits.
Reaching out to them and talking is different from receiving a complete solution to your problem.
Amazon AWS has good technical engineers available, making their customer service reliable.
They route us toward the appropriate team handling Google App Engine or other services, so when there is an issue, the respective team connects and provides support.
The technical support was very quick and responsive, with a direct team line available.
Technical support for Google App Engine is efficient and offers a brilliant solution.
 

Scalability Issues

Sentiment score
7.9
Amazon AWS provides seamless vertical and horizontal scalability, supporting diverse customer needs from startups to large enterprises efficiently.
Sentiment score
7.1
Google App Engine excels in auto-scaling and seamless integration, though deployment times and flexible instances could improve.
Sentiment score
7.8
Salesforce Platform's scalability is highly rated for handling large user bases and offers flexibility in expansion and customization.
The scalability of Amazon AWS is excellent.
Amazon AWS provides strong scalability features, but the scaling process could be made more straightforward.
I would rate the scalability as nine out of ten, appreciating its design that does not require much attention to scaling configurations or costs.
Google App Engine scales well in the standard environment, which automatically handles traffic without manual scaling.
Google App Engine is highly scalable and can integrate easily with other applications.
Salesforce's scalability was not a problem.
Salesforce Platform is absolutely scalable for us.
We are using it globally in thirty countries.
 

Stability Issues

Sentiment score
8.1
Amazon AWS is highly reliable with minimal issues, strong infrastructure, and stability often rated between eight and nine.
Sentiment score
7.7
Google App Engine is reliable with minor issues, requiring minimal maintenance and offering positive user experiences despite occasional disruptions.
Sentiment score
8.1
Salesforce Platform is stable and reliable, with minor issues and performance hitches being exceptions, ensuring high user satisfaction.
I have not experienced any crashing or instability with Google App Engine.
However, large code bases can still cause it to slow down.
I would rate the stability of Google App Engine a perfect 10 out of 10, as it is completely managed by Google.
On occasion, we had to log in and out frequently, open tickets with our IT team for account reconfiguration, or request permissions to access the system.
We have never had any problems with it.
Sometimes the system is stuck when many users are using it.
 

Room For Improvement

AWS users face challenges in cost, support, complexity, security, documentation, and features, with improvements needed in usability and integration.
Users find Google App Engine limited in customization, costly, lacking support, and needing improved tools, language options, and integration.
Salesforce Platform needs improvements in pricing, reporting, integration, UI, automation, scalability, and support for better user experience.
Amazon AWS could improve its user interface to make it more user-friendly, especially for people who are not highly technical.
When using scripts for APIs to fetch data, they don't match the data exactly with the request.
It would be beneficial if Flex services could scale down to zero instances during periods of no traffic.
The pricing is higher compared to alternatives like Kubernetes and Compute Engine.
In the Flex environment, SSH access is not available for private instances.
Salesforce could improve by adding more capabilities to the dashboard, such as additional fields for more filters and more control over what I would like to see.
Salesforce could improve by offering AI features or functionalities to help business decision-makers analyze business history, suggest forward strategies, and participate in events.
Using AI extensively to make the platform easier to use would also be beneficial.
 

Setup Cost

AWS offers scalable, flexible pricing suited for enterprises but requires careful management to avoid high costs from storage and data transfer.
Google App Engine offers competitive pricing for low usage, but costs can rise significantly with higher usage and features.
Salesforce is costly but offers extensive features, flexibility, and benefits, making it worthwhile for large enterprises despite additional costs.
After three to four years, if you are not managing it correctly, you will be paying more than an on-premise solution, which applies to all cloud providers, so you must regularly maintain and manage for efficiency.
Currently, Amazon AWS is known to be on the higher price range because popular and in-demand services often come at a premium.
For F1 usage with 256 MB, it is free.
My GCP billing is about 10 lakh INR per month, and Google App Engine contributes only 25,000 to 30,000 INR.
The pricing of Google App Engine largely depends on the features chosen; if we opt for the standard edition, it is less expensive, while the flexible option incurs more costs due to always having an instance running.
Salesforce Platform may be on the expensive side.
 

Valuable Features

Amazon AWS offers scalable, secure, and flexible cloud services with automation, diverse tools, and excellent support for efficient resource management.
Google App Engine offers scalable, serverless deployment with easy integration, supporting multiple languages to enhance productivity and cost-effectiveness.
Salesforce Platform offers customizable, scalable features with intuitive UI, aiding agile development and efficient automation for enhanced data management.
Amazon AWS offers flexibility and scalability.
One aspect I appreciate in Amazon AWS is their support team, which is excellent.
The solution offers scalability, autoscaling based on user demand, and security, as Google manages all updates and security patches.
Google App Engine offers a cloud-based solution for free, especially for Java, making it a cost-effective option compared to expensive VMs.
I also appreciate the Google App Engine standard environment because it handles traffic scaling without manual intervention.
This integration allows us to manage customers from all aspects in one place, providing a clear view.
Salesforce offers control over the opportunities to see where we are and gives me high-level dashboards on each opportunity stage.
The most valuable features of Salesforce are its level of customization and integration.

Simplifies app development process for businesses
The product simplifies app development processes since once the local development is completed, my company has a common configuration in place where we can specify the requirements to run an application, after which we need to do a one-click GCP deployment for the entire application. In general, the two offer managed deployment options, so we don't have to worry about deployment. In my company, we just configure the servers and check if anything needs to be containerized, after which GCP handles everything for us. A project where Google App Engine scalability was essential was when, recently, my company was involved with Golang to build a web application, after which deploying that application on Google App Engine was really easy. In my company, we also had a Django application in Python, and it was easy to deploy. As my company deals with small-scale projects, the automated scaling feature of Google App Engine is not something we thought about. I wouldn't recommend the product to others unless the potential end users use GCP and have a word with their vendors about their plans. One specific recommendation from me would be that the product's potential uses should stick with a particular vendor. If someone wants a product that is easy to deploy and scalable, then multiple options are available in the market. The product integrates very well with other Google solutions. I rate the overall solution a ten out of ten.

Has customization and integration capabilities which increase efficiency
Salesforce could improve by offering AI features or functionalities to help business decision-makers analyze business history, suggest forward strategies, and participate in events. The previous version had a complicated interface where multiple pages and data entries were required, which was not pleasant for sales teams or business users. Also, deploying Salesforce took a long time, about four to five months, which is not ideal for any business.
