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
6.6
AWS Lambda offers cost efficiency via pay-per-use pricing, serverless design, automatic scaling, and reduced operational expenses.
Sentiment score
7.2
Zadara offers flexible, cost-effective storage expansion, with up to 50% savings and no major hardware investments, despite AWS comparisons.
Employment can be invested in other tasks rather than focusing on regular monitoring tasks or regular repeatable jobs that AWS Lambda can handle.

The project had a calculated cost that was fifteen thousand dollars, and came to an amount of six to seven thousand dollars with Zadara.
Arquiteto De Cloud at Claro Brasil
The cost is not cheaper compared to AWS, and we have not seen the expected return on investment.
Cloud System Engineer at cloud251
I can see the return on investment because we are saving around 15 to 18% of the operational cost when compared to AWS.

Scalability Issues

Sentiment score
7.6
AWS Lambda efficiently scales for varied traffic, integrates with AWS, but may incur higher costs for extensive use.
Sentiment score
7.9
Zadara provides seamless, scalable storage solutions with cost-effective resource expansion, ideal for dynamic business needs and budget adaptability.
I would rate how scalable AWS Lambda is a nine on a scale from 1 to 10, where 1 would be the lowest and 10 would be the highest level of scalability.
Assistant Manager at a tech vendor with 10,001+ employees
Whenever the number of requests increases, the system automatically scales up to the target we have set and scales down once the requests are resolved.
Co Founder And CTO at Gamucopia Creatives
You can scale it up, but the scalability is restricted to 15 minutes of execution time.
cloud engineer at softwareone
There is no need to worry about scalability because the virtual machine automatically detects the load and then takes the load balance.
AI product lead at Sortis
The Zadara team handled changes to hard drive RAID and the storage that made up all the logical part, and it was very transparent to the end user.
Arquiteto De Cloud at Claro Brasil
Zadara is a fully-fledged platform, and our customers are happy with its use.
Cloud System Engineer at cloud251
 

Stability Issues

Sentiment score
8.1
AWS Lambda is highly rated for reliability and performance, with effective scalability, minor latency issues, and excellent stability.
Sentiment score
7.7
Users praise Zadara's stability and consistency, noting strong failover, smooth updates, and proactive support despite rare glitches.
The security and control side, for what it offered, gave total stability.
Arquiteto De Cloud at Claro Brasil
 

Room For Improvement

AWS Lambda's limitations include execution time, integration difficulties, debugging complexities, and runtime constraints, requiring improved usability and flexibility.
Zadara users recommend proactive updates, enhanced features, improved interfaces, better security, platform compatibility, and AI integration with pricing adjustments.
AWS Lambda needs to improve cold start time.
Co Founder And CTO at Gamucopia Creatives
Regarding scaling, we can add up to 1,000 execution environments for every 10 seconds per function, per region.
Consultant at Deloitte
AWS Lambda could be improved regarding the execution time size, as the duration of execution time is fixed at 15 minutes currently, so we could increase it.
cloud engineer at softwareone
Adding AI capabilities could enhance the offering as well.
Cloud System Engineer at cloud251
Maintenance can also be complicated, especially when deeper troubleshooting requires navigating the CLI and searching for logs.
IT Technical Architect at AVALIS
They currently look like simple PHP interfaces, but they need to customize and work on their interfaces and user interfaces significantly.
AI product lead at Sortis
 

Setup Cost

AWS Lambda pricing is pay-as-you-go, offering free initial usage, appealing for small applications and cost-effective for startups.
Zadara offers simple, competitive pricing aligned with IaaS, with flexible billing but has regional cost concerns in South Africa and Ethiopia.
AWS Lambda pricing is high, similar to the servers for S3 buckets.
Python Developer at a consultancy with 5,001-10,000 employees
Based on the execution and time duration of execution, it is much cheaper than expected.
cloud engineer at softwareone
The pricing is considered expensive.
Cloud System Engineer at cloud251
 

Valuable Features

AWS Lambda excels with serverless architecture, automatic scaling, cost-effective pricing, and seamless integration with other AWS services.
Zadara excels in cloud integration, offering flexible deployments, advanced management, multicloud support, and predictable costs for diverse customer needs.
Automatic scaling is a valuable feature. When the number of requests increases, the system automatically scales up to the target we have set and scales down once the requests are resolved.
Co Founder And CTO at Gamucopia Creatives
As it is serverless, AWS Lambda has more scope for building scalable architectures.
Consultant at Deloitte
What I appreciate most about AWS Lambda is that you do not need to purchase the entire service; it only charges you whenever you call that API, which is excellent.
Python Developer at a consultancy with 5,001-10,000 employees
Zadara's impact on scalability and its competitive pricing compared to other market players positively affect my organization.
Analyst Level 3 at a comms service provider with 10,001+ employees
The most valuable feature is its storage management capability.
Cloud System Engineer at cloud251
Zadara's troubleshooting feature is very valuable for me.
IT Technical Architect at AVALIS

Featured Reviews

Rajaraman Ramachandran - PeerSpot reviewer
Co Founder And CTO at Gamucopia Creatives
Has enabled us to manage compute resources efficiently while supporting multiple languages
AWS Lambda needs to improve cold start time. Some AWS Lambda functions require a cold start, and if you need AWS Lambda to provide quick responses, you need some of the AWS Lambdas to be always on, which is risky. We need AWS Lambda's cold start time to be reduced so that we can use it much faster than now. We need a better way to handle the cold start. We should be able to start AWS Lambda much before in a predictable way instead of just calling and then having it start.

Hybrid data migration has reduced costs and now needs stronger security and database integration
I would like to share something that I believe could improve Zadara's process, which is the issue of communication with databases. Today we have MongoDB as a cloud service, so integration with databases in Zadara would bring better performance in connection in SaaS models and in dynamic models that could bring a platform and a solution that could increase Zadara's usage in the market and in its business scope. Zadara can improve in the database integration area as I mentioned. Zadara can have better dynamism such as MongoDB in SaaS and bring this better dynamism by connecting and offering it within the clouds as a possibility of block storage within that partner cloud, such as AWS EBS, Google's cloud storage, or something within Azure. Creating a stronger partnership where this block storage can become an API connectable across various clouds but native to those clouds would be beneficial. I noticed simplicity in the security part during the time I used Zadara, so I believe Zadara's security needs to improve to provide more and deliver more security visibility to the end customer so that they feel more secure with data encryption and attack protection. A WAF on the API connection that goes through greater protection, something along those lines, could help guarantee that the data is protected by Zadara.
