+
+Apache Cassandra is the open source NoSQL database for mission critical data.
Today the community announced findings from a comprehensive global survey of
901 practitioners on Cassandra usage. It’s the first of what will become an
annual survey that provides a baseline understanding of who, how, and why
organizations use Cassandra.
+
+
+ "I saw zero downtime at global scale with Apache Cassandra. That's a
powerful statement to make. For our business that’s quite crucial." -
Practitioner, London
+
+### Key Themes
+
+**Cassandra adoption is correlated with organizations in a more advanced stage
of digital transformation.**
+
+People from organizations that self-identified as being in a “highly advanced”
stage of digital transformation were more likely to be using Cassandra (26%)
compared with those in an “advanced” stage (10%) or “in process” (5%).
+
+**Optionality, security, and scalability are among the key reasons Cassandra
is selected by practitioners.**
+
+The top reasons practitioners use Cassandra for mission critical apps are
“good hybrid solutions” (62%), “very secure” (60%), “highly scalable” (57%),
“fast” (57%), and “easy to build apps with” (55%).
+
+**A lack of skilled staff and the challenge of migration deters adoption of
Cassandra.**
+
+Thirty-six percent of practitioners currently using Cassandra for mission
critical apps say that a lack of Cassandra-skilled team members may deter
adoption. When asked what it would take for practitioners to use Cassandra for
more applications and features in production, they said “easier to migrate” and
“easier to integrate.”
+
+### Methodology
+
+**Sample.** The survey consisted of 1,404 interviews of IT professionals and
executives, including 901 practitioners which is the focus of this usage
report, from April 13-23, 2020. Respondents came from 13 geographies (China,
India, Japan, South Korea, Germany, United Kingdom, France, the Netherlands,
Ireland, Brazil, Mexico, Argentina, and the U.S.) and the survey was offered in
seven languages corresponding to those geographies. While margin of sampling
error cannot technically be cal [...]
+
+To ensure the highest quality respondents, surveys include enhanced screening
beyond title and activities of company size (no companies under 100 employees),
cloud IT knowledge, and years of IT experience.
+
+**Rounding and multi-response.** Figures may not add to 100 due to rounding or
multi-response questions.
+
+### Demographics
+
+Practitioner respondents represent a variety of roles as follows: Dev/DevOps
(52%), Ops/Architect (29%), Data Scientists and Engineers (11%), and Database
Administrators (8%) in the Americas (43%), Europe (32%), and Asia Pacific
(12%).
+
+
+
+Respondents include both enterprise (65% from companies with 1k+ employees)
and SMEs (35% from companies with at least 100 employees). Industries include
IT (45%), financial services (11%), manufacturing (8%), health care (4%),
retail (3%), government (5%), education (4%), telco (3%), and 17% were listed
as “other.”
+
+
+
+### Cassandra Adoption
+
+Twenty-two percent of practitioners are currently using or evaluating
Cassandra with an additional 11% planning to use it in the next 12 months.
+
+Of those currently using Cassandra, 89% are using open source Cassandra,
including both self-managed (72%) and third-party managed (48%).
+
+Practitioners using Cassandra today are more likely to use it for more
projects tomorrow. Overall, 15% of practitioners say they are extremely likely
(10 on a 10-pt scale) to use it for their next project. Of those, 71% are
currently using or have used it before.
+
+
+
+### Cassandra Usage
+
+People from organizations that self-identified as being in a “highly advanced”
stage of digital transformation were more likely to be using Cassandra (26%)
compared with those in an “advanced” stage (10%) in “in process” (5%).
+
+Cassandra predominates in very important or mission critical apps. Among
practitioners, 31% use Cassandra for their mission critical applications, 55%
for their very important applications, 38% for their somewhat important
applications, and 20% for their least important applications.
+
+
+ "We're scheduling 100s of millions of messages to be sent. Per day. If
it's two weeks, we're talking about a couple billion. So for this, we use
Cassandra." - Practitioner, Amsterdam
+
+
+
+### Why Cassandra?
+
+The top reasons practitioners use Cassandra for mission critical apps are
“good hybrid solutions” (62%), “very secure” (60%), “highly scalable” (57%),
“fast” (57%), and “easy to build apps with” (55%).
+
+
+ “High traffic, high data environments where really you're just looking for
very simplistic key value persistence of your data. It's going to be a great
fit for you, I can promise that.” - Global SVP Engineering
+
+
+
+For companies in a highly advanced stage of digital transformation, 58% cite
“won’t lose data” as the top reason, followed by “gives me confidence” (56%),
“cloud native” (56%), and “very secure” (56%).
+
+ "It can’t lose anything, it has to be able to capture everything. It can’t
have any security defects. It needs to be somewhat compatible with the
environment. If we adopt a new database, it can’t be a duplicate of the data we
already have.… So: Cassandra." - Practitioner, San Francisco
+
+However, 36% of practitioners currently using Cassandra for mission critical
apps say that a lack of Cassandra-skilled team members may deter adoption.
+
+
+ “We don’t have time to train a ton of developers, so that time to deploy,
time to onboard, that's really key. All the other stuff, scalability, that all
sounds fine.” – Practitioner, London
+
+When asked what it would take for practitioners to use Cassandra for more
applications and features in production, they said “easier to migrate” and
“easier to integrate.”
+
+
+ "If I can get started and be productive in 30 minutes, it’s a no brainer."
- Practitioner, London
+
+### Conclusion
+
+We invite anyone who is curious about Cassandra to test the [4.0 beta
release](https://cassandra.apache.org/blog/2020/07/20/apache-cassandra-4-0-beta1.html).
There will be no new features or breaking API changes in future Beta or GA
builds, so you can expect the time you put into the beta to translate into
transitioning your production workloads to 4.0.
+
+We also invite you to participate in a short survey about [Kubernetes and
Cassandra](https://docs.google.com/forms/d/e/1FAIpQLScdoTCMxsDwRzt-U898fVmeksBlAf5fud2GVsGqC0T_IQz2Tg/viewform?usp=sf_link)
that is open through September 24, 2020. Details will be shared with the
Cassandra Kubernetes SIG after it closes.
