Challenges experienced by community health workers and their motivation to attend a self-management programme
Community health workers (CHWs) are change agents expected to assist in
decreasing the global burden of disease in the communities they serve. However, they
themselves have health risk behaviours, which predispose them to non-communicable diseases
and thus need to be empowered to make better health choices. There is a gap in literature
detailing the challenges faced by CHWs in addressing their own health risk behaviours.: This study aimed to explore the challenges experienced by CHWs in carrying out their
daily duties and the motivating factors to join a self-management programme
Cloud-scale VM Deflation for Running Interactive Applications On Transient Servers
Transient computing has become popular in public cloud environments for
running delay-insensitive batch and data processing applications at low cost.
Since transient cloud servers can be revoked at any time by the cloud provider,
they are considered unsuitable for running interactive application such as web
services. In this paper, we present VM deflation as an alternative mechanism to
server preemption for reclaiming resources from transient cloud servers under
resource pressure. Using real traces from top-tier cloud providers, we show the
feasibility of using VM deflation as a resource reclamation mechanism for
interactive applications in public clouds. We show how current hypervisor
mechanisms can be used to implement VM deflation and present cluster deflation
policies for resource management of transient and on-demand cloud VMs.
Experimental evaluation of our deflation system on a Linux cluster shows that
microservice-based applications can be deflated by up to 50\% with negligible
performance overhead. Our cluster-level deflation policies allow overcommitment
levels as high as 50\%, with less than a 1\% decrease in application
throughput, and can enable cloud platforms to increase revenue by 30\%.Comment: To appear at ACM HPDC 202
