Apps are Hamstrung by Today’s Database Structure
• 1:1 tie between app and database
• Database = common source of outage
− Planned (maintenance) and unplanned
• Failover causes app errors
• Scaling is challenging and costly

ScaleArc – Enabling An Agile Data Tier, w/ Zero Downtime
• Database traffic management software
− Inserts between apps and databases
− Provides an abstraction layer
• Deploys transparently, in minutes
• Fastest, most cost-effective path to
higher availability and scale
• Supports full range of SQL offerings

Challenges in Cloud Deployments
• Smaller instance sizes
• Inability to architect failover mechanisms
− No support for DNS or IP migration
• Lack of geo control
• Slow performance across WAN boundaries

Key Value Props for ScaleArc in the Cloud
• Enables simple application migration
− Move enterprise workloads to the cloud with no app changes
− Aggregate smaller cloud database instances to behave like one large server
• Provides high-availability solutions with auto failover
− Within one locale or across regions/availability zones
• Delivers high-performance – for cloud and hybrid deployments
− No performance compromise for apps in the cloud
− Supports app in the cloud, database on prem
• Solves future scaling issues
− Scale up and scale out without any app modifications

Top Use Cases – Business Perspective (Sales Rep)
#1 – Help me use what I am paying for
• Use both primary and failover database servers (database load balancing)
#2 – Stop my app from locking up during database failover
• Leverage auto failover without having to reboot app servers
#3 – Help me scale out
• Simply add another database server to the pool to get more capacity
#4 – Speed up my slow database
• Split read vs. write queries and cache various reads

13
Top Three Use Cases – Technical Perspective (SE)
#1 – Continuous application availability
• Customers have implemented failover, but it leaves the app in shambles –
ScaleArc enables the app to survive a database failover
#2 – Visibility
• ScaleArc exposes the query request/response relationship between the
application and the database, especially critical for cloud deployments
#3 – Performance
• ScaleArc’s connection multiplexing, connection management,
authentication offload, caching, and seamless failover speed throughput

ScaleArc performs
read/write split

Upon database
failure, ScaleArc
queues queries

ScaleArc directs
queries to new write

Apps see delay but
not errors

ScaleArc Also Improves Availability for Single Servers
Database offload capabilities
• Connection management
− Multiplexing and other
features smooth input to
server to improve efficiency
• Caching
Sysbench Response Time
Faster through ScaleArc
than directly to database
− NoSQL cache accelerates
response time for related
app and offloads database
to better serve non-cached
content
